Joy & Paddling offers paddling-inspired clothing for everyday wear. No UPF rating or quick-drying performance has been verified for our printed T-shirts. Check each product page for its actual fabric, sizing and care details; choose separate technical clothing suited to your paddling conditions.

TL;DR:

  • Choose garments labeled UPF 50 or higher: wet white cotton drops from about UPF 7 to UPF 3, while quick drying synthetics move sweat.
  • Dress for water temperature: below 60°F (15.5°C), wear a wetsuit or immersion gear; above 70°F (21°C), quick drying synthetics are typically enough.
  • During intense heat, drink about 1 to 2 liters per hour, and schedule paddles outside peak UV hours, roughly 10 a.m. to 4 p.m.
  • Try your PFD with your paddling clothes at home, since thick fabric and shoulder seams can rub during a long trip.
  • PVA cooling towels can stay cool for 30 to 90 minutes depending on humidity, but humid conditions require frequent rewetting.

Which hot-weather kayaking clothes should you grab before launch?

Think in layers of priority. Sun protection comes first, cooling second, comfort third. Here is the short list we check before every hot-day paddle:

  • UPF long-sleeve shirt: it covers your arms and shoulders for hours, which sunscreen alone cannot do once it washes off.
  • Wide-brim hat, or cap plus neck gaiter: your face, ears and neck take the most reflected sun off the water.
  • Polarized sunglasses with a retainer strap: they cut glare and stay put if you flip or lean over.
  • Quick-dry shorts or thin pants: anything that dries fast keeps you from chafing and overheating.
  • Water shoes: they protect your feet on launches and wet ramps.
  • A PFD that fits over your clothes: try your shirt and life jacket together at home, so shoulder seams and thick fabric do not rub.
  • Water, plus electrolytes: plan to drink regularly in strong heat.
  • Cooling towel or frozen bottle: a cold bottle doubles as a drink and a neck cooler.

Two packing tips make the day smoother. Keep your sunscreen, snacks and phone bag in a deck bag you can reach without unclipping anything. And stash a spare shirt in a dry bag, because a clean, dry tee is the best thing to pull on after a long paddle.

Why do UPF and quick-dry fabrics matter, and how do you choose them?

Clothing is the most dependable sun protection on the water because it does not wear off. A UPF 50 fabric blocks about 98% of solar radiation, and the Skin Cancer Foundation requires at least UPF 50 for its Seal of Recommendation. Dermatologists also say UPF 50+ is rated excellent, with UPF 30 to 49 counted as very good.

Cotton is the usual trap. A standard white cotton T-shirt gives only about UPF 7 when dry and about UPF 3 when wet, so a splash or a sweaty back turns it into very little protection. It also stays heavy and soggy, which is miserable in the sun. Our own UPF clothing guide goes deeper on what happens to protection once a garment is soaked. Guidance for anglers makes the same point about how UPF 50 shirts compare with sunscreen.

Fabric choice matters as much as the label. Experienced paddlers prioritize moisture management over color: a loose, light UPF 50+ synthetic sun shirt can keep you cooler than a light-colored cotton one, because synthetics move sweat and dry faster. Tight weave helps too, since dark, tightly woven fabrics are generally more protective than loose, thin ones.

What to look for on the tag and the garment:

  • A stated UPF number, ideally 50 or higher.
  • Polyester or nylon blends labeled quick-dry or moisture-wicking.
  • Flat seams that will not dig in under a PFD strap.
  • Thumb loops, so sleeves stay over your hands and wrists.
  • Vents or mesh panels where the garment will not sit under straps.

Check the manufacturer’s instructions for the garment’s tested sun protection, including any stated limits when wet or stretched. Do not assume the protection stays the same after soaking.

What hats and sunglasses protect you without cooking your head?

The CDC’s travel guidance recommends wide-brimmed hats to shade your face, ears and neck, and notes that water reflects extra UV at you. A cap leaves your ears and neck exposed, so pair it with a gaiter or neck flap if you go that route. Sunglasses matter just as much, and dermatologists underline the value of UV-blocking lenses.

  • Choose ventilation: mesh panels or a vented crown let heat escape. Our guide to wearing a black hat in the sun shows how airflow decides comfort more than color does.
  • Add a chin strap: wind and a lean over the gunwale will take an unsecured hat.
  • Wet it down: dunking your hat and putting it back on is the oldest cooling trick on the water.
  • Cover your scalp: thin hair and parts burn fast, and our scalp protection tips cover what stays put.
  • Choose polarized, UV-blocking lenses: they cut glare and show you what is under the surface. Add a retainer strap.

Pair your hat with a good sunscreen routine. A reef-safe option and reapplication habits from a sun protection guide for outdoor activities apply just as well to paddlers.

What are the best shorts, pants and water shoes for hot-weather paddling?

Cotton fails on your lower half too, because it retains water, loses insulation and gets heavy. Quick-dry synthetics are the standard answer.

  • Board-style paddle shorts: these dry fast and give your legs room to move on the seat.
  • Lightweight nylon hiking shorts: a good everyday option that works on the trail and the water.
  • Thin convertible sun pants: zip-off legs let you cover up at midday and cool off later, and UPF-rated fabric is the better pick when your legs sit in the sun for hours.
  • Water shoes: pick closed-toe styles with grippy soles for wet ramps and rocky launches.
  • Secure sandals: fine on sandy or muddy put-ins if the straps hold your heel.
  • Neoprene booties: better for cold water or sharp shorelines, but they trap heat, so skip them on warm days unless the terrain demands them.

If your kayak seat leaves your thighs exposed, choose pants or sunscreen for those hours. Your lap gets the full sun, and reflected light from the water makes it worse.

How do you dress for the water and stay safe in the heat?

Dress for the water, not just the air. Below 60°F (15.5°C), you need a wetsuit or specialized immersion gear, while above 70°F (21°C), quick-dry synthetics like UPF shirts and board shorts are typically enough. A capsize in cold water can turn a warm afternoon dangerous even when the air feels fine.

Drink about 1 to 2 liters of fluid per hour during intense heat, and avoid peak UV hours, roughly 10 a.m. to 4 p.m., when you can. Plan your launch around that window.

  • Launch early or late: dawn and late afternoon give you cooler air and softer light, and fewer people on the water.
  • Carry more water than you think: heat illness can be fatal, and early signs are cramps, headaches, weakness and nausea.
  • Use shade and rest: pull into a cove or under trees on long hot paddles.
  • Check heat risk tools: the National Weather Service’s heat stress guidance suggests acclimatization and scheduling strenuous effort earlier or later in the day.
  • Know when to quit: if you feel dizzy or stop sweating, get to shore, cool down and rehydrate before going on.

How can you cool down with evaporative cooling and cold bottles?

Water gives you free air conditioning on the boat, and a few small habits make it work harder. Paddlers soak a hat or neck gaiter in cool water and put it back on, which can noticeably lower how hot you feel. The same source notes that PVA cooling towels stay cool for 30 to 90 minutes depending on humidity, so they work best in dry air and need re-wetting often in humid conditions.

  • Soak and re-wear: hat, gaiter, or sleeves, every time you pass clear water.
  • Freeze a bottle the night before: it chills your drink for hours and works as a cold pack for your neck or wrists.
  • Bring electrolytes: a drink mix or salty snack keeps you from cramping when you sweat a lot.
  • Pack a small spray bottle: a quick mist on your face and arms helps between dips.
  • Schedule swim breaks: when the water is cooler than your skin, a short swim resets your body temperature.
  • Pace yourself: ease off before you feel overheated, because recovering costs more time than slowing down.

Pro Tip: Wet the back of your neck and your wrists first. Both spots sit close to blood vessels, so a cool cloth there is the fastest way to feel better.

What should be in your packing checklist for a hot-weather paddle?

Use this order when you load your kit, from must-haves to nice-to-haves:

  1. PFD: wear it, don’t just carry it.
  2. Water: carry plenty and drink regularly in strong heat.
  3. Sunscreen, SPF 30 to 50: apply it to any skin your clothes do not cover and reapply on schedule.
  4. Hat and polarized sunglasses: add retainer straps to both.
  5. Waterproof phone bag: keeps your phone safe and within reach.
  6. Spare quick-dry shirt: dry clothes lift your mood after a long day.
  7. Cooling towel, electrolytes and a small first-aid kit: the comfort and backup layer.

When you get home, rinse performance fabrics in fresh water and hang them to dry. Our post-paddle drying checklist covers keeping clothes fresh, and our guide to removing sunscreen stains from paddling gear helps if your tee picks up marks.

Which paddling gloves work in hot weather?

Gloves sound like a cold-weather item, but they help in summer too. Hours of gripping a paddle shaft cause blisters, and the backs of your hands sit in direct sun all day, which means sunburn.

Look for thin, breathable gloves with open fingers or a mesh back, so heat can escape. Fingerless styles keep your fingertips free for gear and knots while still protecting your palms. Check for a snug fit, because loose gloves slide and create the same friction you wanted to avoid.

Choose a grippy palm that holds up when wet, since a slick shaft makes you squeeze harder. A UPF-rated back is a bonus. Where gloves feel too warm, thumb loops on a UPF sleeve cover the backs of your hands without adding a layer.

Dip them in water as you paddle, just like your hat. A wet glove cools your hands and keeps the fabric from drying stiff. Break in a new pair on a short paddle first, so you find any rubbing spots before a long day.

Can you look good and stay protected on the water?

You do not have to pick between style and sun protection. A bold print on a UPF, quick-dry shirt works just as well as a plain one, and it makes the day more fun. I always reach for sleeves with thumb loops and a hat with a chin strap on long flat-water days, because those two choices solve the most problems at once. Prioritize hydration and shade, then wear whatever makes you smile.

FAQ

What should you not wear when kayaking in hot weather?

Skip cotton, jeans and heavy fabrics. Cotton retains water, loses its insulating ability and becomes heavy, which feels worse in the sun. Also avoid flip-flops that slip off and dark, thick layers that trap heat.

Should you wear gloves when kayaking in summer?

They can help. Thin, breathable gloves with a grippy palm prevent blisters on long paddles, and a UPF back protects your hands from sunburn. Pick fingerless or mesh styles so your hands stay cool.

What should you wear for kayaking when the water is cold?

Dress for the water, not just the air. For cold water, choose a wetsuit or specialized immersion gear, plus a synthetic base layer. Avoid cotton, since it stays wet and chills you quickly.

Can you kayak in the winter?

Yes, with the right gear and a plan. Cold water is the main risk, so wear immersion protection, paddle with a partner and stay close to shore. If a capsize would put you in water below 60°F (15.5°C), treat it as a cold-weather outing, not a summer one.
