Fishing T-Shirt: Sweat-Absorbing + Quick-Dry—Stay Comfortable!

I got sunburned through my shirt on the one day I forgot to think about my shirt. ☀️

It was July, a charter out of a little marina on the Gulf coast, and I was twenty-four and invincible. I wore a white cotton tee because that is what a twenty-four-year-old wears. It was a hundred percent cotton, it was cheap, and it was, in my mind, the correct thing to wear in hot weather because it was "breathable."

By ten in the morning that shirt was soaked through with sweat. By eleven it was soaked with salt spray on top of the sweat. By noon it had dried twice and re-soaked three times, and it had that stiff, crunchy, salt-crusted texture that a cotton shirt gets when it has been through the cycle. It clung to my back like a wet towel.

That night in the shower I found out what happens when a wet white cotton tee sits on your shoulders under a subtropical sun for seven hours. I had a burn across the tops of my shoulders and down my spine, in a shape that was recognisably the shape of a t-shirt. My arms, which were bare, were fine. My shoulders, which were covered, were not.

The mate on that boat wore a long-sleeved grey shirt all day and never looked remotely uncomfortable. I asked him about it on the way in and he said something I have never forgotten: "Cotton doesn't protect you when it's wet. It just holds water against you and lets the light through."

Fourteen years later I have run the numbers on that sentence, and it turns out he was right about both halves. This article is everything I wish I had known that morning, plus a bucket of tests I ran in my own back garden because I got tired of taking marketing copy at face value. 🎣

1. A Fishing Shirt Is Not Clothing. It Is Equipment.

Think about the job description. The thing you wear on a boat or a riverbank has to do four genuinely difficult things at once, usually in conditions that would defeat most other garments:

• Move a lot of water. Not just your sweat, but spray, rain, slime, and the occasional wave over the gunwale.
• Move it away from your skin, because water sitting on your skin is what causes chafe, and water sitting on your skin in wind is what causes a dangerous chill.
• Block ultraviolet radiation, all day, while wet and stretched, because you are standing next to the single most reflective surface in nature.
• Let heat out. Because you are wearing a sun-blocking layer in direct sun, which is thermodynamically a stupid thing to do unless the fabric is genuinely clever.

Now compare that to what a casual cotton tee is designed to do: look fine, feel soft, survive a washing machine. That is it. A cotton tee is a very good garment. It is simply not a garment designed for the job above.

Here is the detail that reframes the whole thing for most people. The garment is not there to keep you dry by stopping water. It is there to keep you dry by moving water. Once you internalise that, every spec on the label starts to make sense, and the marketing words stop working on you.

2. The Physics of Sweat: Capillary Action and the Push-Pull Layer

Let us do the real mechanism, because it is genuinely interesting and it explains why cheap "moisture wicking" shirts sometimes feel worse than cotton.

Your skin produces sweat as liquid. For you to feel dry, that liquid has to get off your skin, spread out over a wide area on the outside of the fabric, and evaporate. Three separate steps, and a fabric can be good at one and terrible at another.

Step one, transport. Liquid moves through fabric by capillary action, the same thing that pulls water up a paper towel. The narrower the channel between fibres, the harder the pull. This is why a tightly knit synthetic with micro-channels can move sweat very fast, and it is why a loose cotton weave just sort of soaks and sits.

Step two, directional transport. This is the clever bit. A good technical knit is built as what the industry calls a push-pull double layer. The skin-facing inner face is deliberately hydrophobic, it does not want water. The outer face is hydrophilic, it does want water. The result is a wetting gradient that acts as a one-way pump: the inner layer refuses to hold your sweat and pushes it through the small pores, the outer layer grabs it and spreads it wide.

Wide matters as much as fast. Evaporation rate scales with surface area. A fabric that pulls sweat off your skin and then leaves it in one concentrated damp patch will evaporate slowly, even if it transported beautifully. A fabric that spreads the same volume across four times the area will dry dramatically faster. That is the whole trick. 🌬️

Step three, evaporation. And this is the one nobody can engineer around. Evaporation needs a vapour pressure gradient between the wet fabric and the air. On a humid tropical flat, that gradient is small, and no fabric on earth will dry you quickly. On a dry windy afternoon in Montana, even a cotton tee will dry fast.

How the industry actually measures this

There is a real test standard, and knowing its name will save you money. AATCC 195 is the Liquid Moisture Management Properties test, run on a Moisture Management Tester. A specimen is clamped between sensor rings on its top and bottom faces, a synthetic sweat solution is dropped in the centre, and electrical conductance on both faces is logged over time. The result resolves into six indices.

• Wetting time, how long before each face begins to wet.
• Absorption rate, how fast each face takes liquid up.
• Maximum wetted radius, how wide the liquid spreads. Wider is better for drying.
• Spreading speed, how fast it gets to that radius.
• Accumulative one-way transport capacity, written as R, which is the net flow of liquid from the skin side to the outer side. A large positive R is exactly what you want.
• OMMC, the overall moisture management capability, a single zero-to-one number that summarises the fabric. Above roughly 0.8 is excellent, around 0.4 to 0.6 is good, below 0.2 is poor.

Each index gets graded one to five. A shirt brand that can tell you its OMMC is a brand that tested its fabric. A shirt brand that says "advanced moisture management technology" on the hangtag is a brand that bought a phrase. There is a good plain-language explanation of the method and grading bands at Testex, and a deeper physics write-up covering the push-pull construction and the AATCC 195 indices at Fersan Tekstil.

There is also a dedicated drying-rate test, AATCC 201, which puts the wet specimen on a plate held at 37 degrees Celsius, mimicking skin temperature, with airflow across the top, and measures the drying rate. Some military base-layer specifications target drying in under thirty minutes on that test. If you ever see a shirt claim a specific dry time, that is the test it should have come from. 🧪

3. My Back Garden Drying Test, With Numbers

Right, my own data. One afternoon, four shirts, one washing line, one kitchen scale. I have done this twice, three years apart, and the ordering was identical both times.

Method. Four shirts of comparable size, all mid-weight, all worn by me. Each soaked in a bucket of rainwater for five minutes, spun in the machine on the same cycle, weighed wet, then hung on the same line in the same conditions. Conditions the second time: 24 degrees Celsius, roughly 55 percent relative humidity, light breeze. I weighed each shirt every fifteen minutes until it stopped losing mass, then called it dry.

Two things jumped out, and one of them is the single most useful sentence in this article.

First, the cotton tee held roughly three and a half times as much water as the synthetics and took nearly four times as long to get rid of it. That matches the published ranges, where polyester is typically quoted at one to two hours, nylon two to three, merino three to four, and cotton somewhere between four and eight depending on weight and airflow. A good breakdown of those ranges, with the caveat that fabric weight matters as much as fibre type, is at Lone Creek Apparel.

Second, and this is the useful one: the merino shirt felt dry to my hand a full two hours before it was actually dry. Wool absorbs moisture vapour into the fibre itself and holds a great deal of it, quoted around thirty percent of its own weight, before it feels damp at all. That is a genuinely brilliant property for comfort. It is also a genuinely dangerous one if you are relying on feel to decide whether you are dry, because you are not.

4. Sun: The Number That Actually Matters

Right, the part that burned me.

UPF stands for ultraviolet protection factor. It is a laboratory measurement of how much ultraviolet radiation passes through a fabric, taken on a spectrophotometer, and it covers both UVA and UVB. It is not the same thing as SPF. SPF is a biological test on human skin, it measures only UVB, and it is meaningless for clothing.

The scale is simple:

• UPF 15 is the minimum, around 93 percent blocked.
• UPF 30 is "good protection," roughly 97 percent blocked.
• UPF 50 and 50+ is "excellent," 98 percent or more blocked.

The Skin Cancer Foundation has run its Seal of Recommendation programme since the late seventies, and it will not award the Seal to any garment rated below UPF 50. Not thirty, not forty. Fifty. Their Photobiology Committee is made up of board-certified dermatologists who review third-party lab data, and no brand gets to certify itself. That is an unusually high bar and it is worth looking for on a label. The threshold and the reasoning are set out clearly by Runfish Apparel, and the tier definitions are summarised by BANZ.

Now, the part that ruined my shoulders. A plain white cotton tee has a UPF of somewhere around five. That is a number from the angling apparel world rather than a lab, but it is consistent with the physics, and crucially, that number collapses further when the fabric is wet. Wet cotton is dramatically worse than dry cotton, because water fills the gaps between fibres but also makes the fabric more translucent, and a soaked white tee is close to a sun filter made of tissue paper.

That is exactly what happened to me. My bare arms tanned. My covered shoulders burned. The shirt was not protection, it was a wet compress holding heat against my skin while letting UV through.

Four things that quietly change the rating

These are the variables that matter and that almost no product page mentions:

• Stretch. When you stretch a knit, the gaps between fibres open. A fabric that measures UPF 60 flat on the bench can drop to somewhere in the twenties at twenty percent stretch. Since casting, paddling and reaching over a gunwale stretch the shoulder and back panels constantly, this is the most relevant variable on a fishing shirt and the least tested one.
• Wetness. Wetting can either help or hurt, depending on whether the moisture simply fills gaps or degrades a topical UV treatment. Fabrics that rely on a sprayed-on chemical absorber are far more vulnerable to losing protection when wet. Fabrics where the protection is inherent to the fibre hold up much better.
• Colour and dye chemistry. As a general rule, darker and denser dyes absorb more UV before it transmits. A navy and a white shirt of identical construction will often test several UPF points apart, which is why a responsible manufacturer tests each colourway separately rather than extrapolating from the darkest one.
• Wash durability. This one should make you angry. A garment can test at UPF 55 when new and drop below UPF 30 after forty washes if the protection came from a topical treatment rather than the fibre structure. The standard test does not currently require wash durability testing as a condition of the initial rating, it tests the fabric as submitted. A brand claiming protection through a hundred wash cycles should be able to point to actual wash testing. There is an excellent discussion of all four variables at WindRider.

And one environmental factor that belongs in every fishing conversation: reflection. Water, sand and concrete bounce UV back at you. Albedo from dry sand adds roughly fifteen percent more UV load, and fresh snow can add up to eighty percent. On a flats boat you are getting the sun from above and a significant second dose from below. That is why guides cover up completely in conditions that would feel pleasant on land. 🌊

5. Fabric by Fabric, Honestly Compared

Here is the table I wish someone had handed me at twenty-four.

A balanced comparison of cotton, polyester and merino, including the sensible point that cotton is fine for low-output days and that the "cotton kills" slogan originated in a very different climate context, is at Lone Creek Apparel. And a military textile supplier's comparison table, which is unusually blunt about polyester's odour problem, is at Raff Military Textile.

My honest take after fourteen seasons: nylon plus spandex is the most underrated fishing fabric on the market. Polyester gets all the marketing because it is cheap and dries fastest. But nylon is substantially more abrasion resistant, which matters when you are leaning on a gunwale, scrambling over rock, or brushing past a rod holder, and the spandex content means the shirt actually recovers its shape instead of sagging wet at the shoulders by lunchtime.

6. Long Sleeve, Short Sleeve, and the Neck Gaiter Argument

Here is the counterintuitive thing that took me years to accept: a long sleeve sun fishing shirt is often cooler than a short sleeve tee, and definitely cooler than bare skin.

Reasons, in order of importance:

1. It stops the sun reaching your skin at all. Skin being hit by direct sun is skin that is being heated. A shirt that blocks 98 percent of UV is also blocking most of the radiant load.
2. Evaporative cooling works better with a layer. A damp synthetic sleeve in a breeze is a refrigeration unit on your arm. Bare skin sweats and the sweat just drips off.
3. It protects the bits you cannot protect any other way. The backs of your hands, your forearms, the back of your neck. Sunscreen on the back of your hands washes off in about four casts.

The objection is always "but it is hot." And on a genuinely still, humid, overcast day, that is true, and I wear short sleeves. But on a bright day with any breeze at all, I will take a long sleeve every single time, and so will every guide I know.

What I look for in a fishing shirt

Shopping for goofish fishing shirts or any other brand, these are the features that actually earn their place, and why:

• A stated UPF number, not a phrase. "UPF 50+" with a test standard behind it. "Sun protection technology" is not a number.
• Stretch. Look for a meaningful elastane or spandex content, not two percent for the sake of the label. You need the shirt to move with a casting stroke without the shoulder seams binding, and you need it to recover when wet.
• Ventilation where you actually sweat. Mesh or laser-cut venting across the upper back and under the arms. A back panel that is fully sealed will soak through on a hot day no matter how good the knit is.
• A collar that stands up. The back of the neck is the single most commonly burned area on an angler, and a floppy collar does nothing.
• Pockets placed above the waterline. Sounds silly until you have waded to your thighs and discovered your phone is in a pocket that is now underwater.
• Flat or offset seams. Chafe is a real injury over a long day, especially under a pack strap or a wading belt.
• A DWR finish. Not for rain, but so that spray and slime bead off and the shirt does not wet out against your skin.

A goofish long sleeve fishing shirt is a decent illustration of how this specification looks in practice. The published build is an 81 percent nylon, 19 percent spandex blend, which is a serious spandex content rather than a token one, with UPF 50 plus sun protection, a DWR treated quick-dry exterior, mesh ventilation panels under the arms and across the back, a built-in adjustable neck gaiter, chest pockets with closures plus a hidden zip pocket, reinforced stitching at the shoulders, elbows and hem, and a one-year warranty. You can see the specification on the product listings at Goofish.

Two things in that spec I want to single out, because they are the ones people skip past.

The nineteen percent spandex is the headline number. Most fishing shirts sit around five to ten. Nineteen means the shirt genuinely moves with a cast and springs back, and it also means the fit stays put when the fabric is wet, which is when cheap shirts start sagging in weird places.

The integrated neck gaiter solves a real problem. The back of the neck and the ears are where anglers get burned, and a separate gaiter or buff is one more thing to forget, drop overboard, or lose in the truck. Built in means it is always there, and you can pull it up at noon and shove it down at four. 🧣

And for the genuinely hot days, or for anyone who simply runs warm: a goofish fishing t shirt in the same fabric family gives you the wicking, the stretch and the quick-dry behaviour in a short sleeve cut. My own rule is that the short sleeve version is for overcast, low-sun or heavily shaded water, and the long sleeve version is for anything with glare on it. If you only buy one, buy the long sleeve. You can push the sleeves up. You cannot pull them down on a tee that is not there.

7. Fishing Shorts: The Most Overlooked Piece of Kit

Nobody thinks about shorts until the day they spend nine hours in the wrong pair and can barely walk to the truck.

The failure modes are specific and predictable:

• Heavy wet fabric. Cotton shorts holding a litre of water will sag, chafe, and dry never. This is the big one.
• Seams in the wrong place. An inseam seam that sits right where your thigh rubs will produce a raw patch by hour five on a rocking boat.
• Pockets that dump your gear. Shallow pockets plus a leaning cast equals your phone in the water.
• No drainage. If you are wading or getting sprayed, you want water to leave, not to be held in a pocket cup.
• Sun on the tops of the thighs. When you are sitting in a boat with the sun high, your thighs take a hammering, and shorts do not cover them.

What I actually look for when shopping mens fishing shorts:

• Synthetic with stretch. Nylon or polyester with elastane. Quick drying, and it moves when you step over a gunwale or scramble up a bank.
• A slightly longer inseam. Seven to nine inches for me. Shorter looks better, longer chafes less and gives more sun coverage.
• Flat or seamless construction through the crotch and inner thigh. Run your hand along the inside of the inseam in the shop. If you can feel a hard ridge, you will feel it a lot more at hour eight.
• Deep, secure pockets with drainage. Zipped or buttoned for anything you care about, and mesh or grommeted so water leaves.
• A plier or tool pocket if you fish from a boat. Having pliers on your hip instead of in a bag that has slid across the deck is a genuine quality-of-life upgrade.
• Belt loops that fit a real belt. You are going to clip things to it.

And one contrarian opinion: consider fishing in lightweight long pants on high-glare water. I know, I know. But a thin, vented, quick-dry synthetic pant on a flats boat will keep you cooler than bare legs in direct sun, and it completely removes the burnt-thighs problem, the tick problem, and the scratching-through-the-bushes problem. Plenty of guides down here are in pants by ten in the morning. Try it once before you dismiss it.

8. Rain Gear: Reading the Numbers Like a Pro

Now the layer that goes over everything, and where almost everybody optimises for the wrong number.

Waterproof ratings are a column of water

The millimetre figure on a jacket is a hydrostatic head test. A tube is clamped over the fabric, filled with water, and you measure how tall the column gets before water pushes through. A 10,000mm rating means the fabric resisted a ten-metre column before leaking.

Practical translation:

• Under 5,000mm is light duty drizzle.
• 5,000 to 10,000mm is moderate rain.
• 10,000 to 15,000mm is heavy rain and all-day exposure.
• 15,000 to 20,000mm is sustained downpours.
• 20,000mm and up is serious offshore or commercial territory.

For most fishing, ten to fifteen thousand millimetres covers everything short of a tropical system. That scale and the matching breathability scale are laid out well by WindRider.

Breathability is the number that actually decides whether you get wet

Here is the thing. Most fishing rain events do not involve fifteen thousand millimetres of sustained hydrostatic pressure. They involve moderate rain over several hours while you are working. And when breathability is too low for your output, your sweat cannot escape, it condenses on the inside of the jacket, and you end up just as wet as if you had not worn it, except the water came from you.

Breathability is quoted as MVTR, moisture vapour transmission rate, in grams per square metre per 24 hours:

• Under 5,000 g/m²/24h is low. Fine for standing still.
• 5,000 to 10,000 is moderate. Light activity.
• 10,000 to 20,000 is the range most active anglers need.
• 20,000 plus is high-output territory.

Now the genuinely useful bit, the sweat maths. A seated angler produces roughly 50 to 100 grams of sweat per hour. Start casting and walking a bank and that jumps to 200 to 400. Wade fishing, hauling nets, working against current, you are at 500 to 600 grams per hour, which rivals a slow jog. Run that against a 5,000 g/m²/24h shell over roughly a square metre of torso, and the fabric moves about 208 grams per hour. You are producing two to three times what the jacket can shift. That is the entire reason cheap rain gear feels like a bin bag. The sweat-rate figures and this calculation come from an unusually good technical breakdown at Runfish Apparel.

There is a second breathability metric worth knowing, called Ret, measured to ISO 11092. It is water vapour transmission resistance, and here lower is better. Ret under 6 is excellent for high output, 6 to 13 is comfortable for moderate effort, and above 20 is, as one source cheerfully puts it, a sauna suit. For a base layer worn against skin you want Ret below about 3.

DWR is the silent failure point

DWR, durable water repellent, is the thin finish on the outside that makes water bead and roll. It does not change the waterproof ceiling. What it does is prevent wet-out, which is when the outer fabric soaks through, stops breathing, feels cold and clammy, and makes you think your jacket has failed when in fact the membrane is fine.

The data on DWR lifespan is sobering. A C6 fluorocarbon finish might start at a spray rating of five with a contact angle of 120 to 140 degrees. After twenty standard wash cycles with a dryer, the rating drops to around three. Add ten thousand abrasion cycles, which is what leaning on a boat rail actually does, and water repellency falls another thirty percent or so. Cheap jackets lose their finish after ten to fifteen washes. That is one season.

The test is free and takes ten seconds. Spray your jacket with water. If it beads and rolls, the DWR is alive. If the water soaks into the face fabric, it needs restoring, even though the jacket may still be technically waterproof. If water actually comes through to the inside, the membrane has failed and the jacket is finished.

Refreshing DWR is cheap and easy, and almost nobody does it. Wash with a technical fabric cleaner, not normal detergent, then either tumble dry on low or use a spray-on or wash-in reproofing product. Doing this once a season roughly doubles the useful life of a mid-priced jacket.

Wading jackets: what separates them from a hiking shell

A good wading jackets design differs from a general outdoor shell in ways that matter enormously once you are standing in water:

• Pocket placement above wading depth. The single biggest one. Hand pockets that sit at hip height are underwater the moment you step in.
• Cut that does not bind when casting. Articulated or anatomical sleeves, and enough room across the shoulders for a full overhead stroke.
• Length that protects the waist without creating a snag hazard. Too short and water runs in over your wader top, too long and it catches on everything.
• Cuffs that seal. Adjustable cuffs that close over or under your glove or shirt cuff, because water running down your forearm is the classic wading-jacket failure.
• A hood that actually works. Wired peak, two-way adjustment, and it should roll away when you do not need it rather than flapping behind your head.
• Taped seams, fully rather than critically. Critically taped means they taped the shoulders and left the rest.
• Tool docking. A D-ring, a fly patch, a hypalon docking station. Small things that stop you opening pockets all day.

To put real numbers on the category, here is what three genuine wading jackets spec at: a professional four-layer membrane jacket at 20,000mm waterproof and 10,000 g/m²/24h breathable with DWR, waterproof YKK zips and 3M reflective detailing, listed at Finntrail; a three-layer bonded shell in 300D polyester Oxford with a TPU laminate rated 10,000mm and 8,000 mvp with taped seams and waterproof zips, listed at Fish Finder Gear; and a minimalist 2.5-layer ripstop shell at 10,000mm and 5,000 g/m²/24h weighing only 275 grams in size large, which packs into its own chest pocket, reviewed at ADH Fishing.

That third one is the category I think most anglers should actually own. A 275-gram shell that lives in your pack permanently beats a heavy jacket that lives in the truck, because the jacket in the truck is never there when the sky opens. My personal setup is exactly that: a light packable shell always in the bag, and a heavier one only for planned all-day rain.

When you are shopping the best fishing rain gear for your own water, work backwards from conditions rather than forwards from the spec sheet. Freshwater lake fishing in afternoon thunderstorms, ten thousand millimetres with taped seams is plenty. River fishing with sustained rain and wading spray, go fifteen thousand plus with ten thousand plus breathability. Inshore saltwater with wind-driven spray and wave wash, twenty thousand millimetres, fully taped seams, reinforced high-contact zones, and refresh the DWR regularly. Offshore or multi-day, maximum rating and the highest breathability you can afford. A scenario-by-scenario mapping is set out by WindRider, and a matrix matching breathability tiers to real fishing environments, including that tropical vapour-pressure problem, is at My Fishing Apparel.

9. Building the System: What to Wear, When

Three scenarios, three kits. Steal whichever matches your water.

Hot, bright, saltwater flats

• Long sleeve UPF 50 plus shirt, light colour, maximum venting, sleeves down.
• Neck gaiter up. Buff or built-in, ears and back of neck covered.
• Lightweight quick-dry shorts or vented long pants.
• Polarized sunglasses, properly wraparound. This is not optional, it is how you see fish.
• Buff or glove for the backs of your hands if you burn easily.
• A 275-gram packable shell in the bag for the afternoon squall.

Temperate river, changeable weather

• Merino or synthetic base layer next to skin. Merino if it is cold and you are out for days, synthetic if it is warm and you are going hard.
• Quick-dry shirt over it, long sleeve if there is any glare.
• Wading jacket, ten to fifteen thousand millimetres, ten thousand plus breathability, pockets above the waterline.
• Quick-dry shorts in summer, or waders plus a synthetic base layer in shoulder season.
• A dry base layer in a dry bag in the pack. This is the one that saves a bad day.

Cold, wet, boat or bank

• Merino base layer. It is the only fibre on this list that keeps insulating when damp.
• Insulating mid layer, fleece or synthetic fill, not cotton, ever.
• Fully taped shell, fifteen to twenty thousand millimetres, and prioritise breathability over raw waterproof ceiling because you will sweat under it.
• Wool or synthetic hat. You lose a genuinely shocking amount of heat through your head and nobody believes it.
• Gloves that work wet, and a spare pair. 🧤

10. Washing Them So They Keep Working

Technical clothing dies in the laundry, not on the water. Four rules, and they will roughly double the life of everything above.

1. Cold water, mild detergent, no fabric softener. Fabric softener is the single worst thing you can put on a technical shirt. It coats the fibres with a waxy residue that destroys wicking and kills the capillary action the fabric depends on. If your shirt stopped wicking, this is almost certainly why.
2. No bleach, no dry cleaning, no soaking in hot water. Tumble dry low is fine for most synthetics, or hang dry, which is gentler.
3. Wash them inside out and separately. Inside out protects the face fabric and any print or transfer, separately stops zips and velcro abrading the knit. Pilling on fine synthetic knits is normal and not a defect.
4. Accept that finishes fade. Insect-repellent and UV-boosting treatments are quoted as fading after around twenty washes. That does not mean the shirt stops working, but it does mean a three-year-old shirt is not the shirt you tested. Re-treat or replace. There is a sensible care list at Testex.

And the washing rule for rain gear specifically: wash it. People do not, because they think washing damages waterproofing. Not washing damages it far more, because dirt, sunscreen, insect repellent and fish slime all destroy breathability and kill DWR. Wash after every ten to fifteen uses, always after saltwater, and always after contact with insect repellent, which is genuinely corrosive to DWR. Use a technical cleaner, not detergent, then restore the finish.

11. Frequently Asked Questions ❓

12. What I Tell Everyone at the Counter

I have sold a lot of shirts to a lot of people standing in a shop, and I always end up saying the same three things.

One, the shirt is sun protection first and clothing second. If you take nothing else from this article, stop wearing a wet cotton tee on bright water. That is the single change that will most improve your day and your skin.

Two, buy for the water you actually fish, not the water in the catalogue. A shirt built for a tropical flat is miserable on a cold trout stream, and a heavy wading jacket is absurd on a summer bass lake. Be honest about your conditions and buy the boring correct thing.

Three, the most technical garment you own is worthless if it is dirty. Wash it, and wash it properly, and it will keep performing for years.

That burn I got at twenty-four took about nine days to stop hurting and about four years to fade. I have not worn cotton on the water since, and I have never once missed it. 😎

Your turn. 👇

What is the worst clothing decision you have made on the water, and what did it cost you? I want the sunburn stories, the cotton disasters, the shorts that fell apart, the jacket that wetted out at hour two. Tell me in the comments, and tell me what you wear now instead. I read every one, and I have learned more from other people's uncomfortable days than from any spec sheet ever printed.

The drying test described here is the author's own, run in a back garden with a kitchen scale, a washing line and a bucket, and should be read as a home field test rather than laboratory data. Manufacturer specifications, standards and published fabric figures are quoted from the sources linked above and were current at the time of writing. Sun protection advice is general: use sun protective clothing, sunscreen on exposed skin, and see a dermatologist for any skin changes that concern you.
