Understanding Sun Exposure and UPF Ratings on Open Water

Water surfaces act like giant mirrors, reflecting up to 10% to 50% of ultraviolet (UV) radiation back up at you. This means paddleboarders receive a double dose of sun exposure—once directly from the sky, and again from the water’s surface. Even on overcast days, up to 80% of UV rays penetrate cloud cover, making reliable physical protection non-negotiable.

While sunscreen is a necessary tool, it washes off, sweats away, and requires constant, messy reapplication. Ultraviolet Protection Factor (UPF) clothing solves this by providing continuous, reliable protection that does not degrade throughout the day. A UPF 50 rating, for instance, allows only 1/50th of the sun’s UV radiation to pass through the fabric, effectively blocking 98% of harmful rays.

For paddlers over 45, managing this cumulative exposure is critical for preserving energy levels and skin health. Overheating and UV damage accelerate fatigue, making the journey back to the launch ramp significantly harder. Proper apparel acts as passive climate control, keeping core temperatures stable so energy can be focused on paddling.

Sun Hat – Sunday Afternoons Ultra Adventure Hat

A high-quality sun hat is the first line of defense, shading the eyes, face, and neck from direct glare. On a paddleboard, wind is a constant variable, meaning a standard beach hat will quickly fly off or flop into your eyes. You need a structured, secure hat that stands up to a breeze while offering comprehensive coverage.

The Sunday Afternoons Ultra Adventure Hat is a premier choice for full-day paddling. It features a wide, reverse-clamshell brim that protects the eyes without blocking upward vision, paired with an integrated six-inch neck cape. The fabric is rated UPF 50+, ultra-lightweight, and designed to float if a sudden gust knocks it into the water.

• Brim Width: 3.25 inches with a 6-inch neck cape
• UPF Rating: 50+ certified sun protection
• Material: 100% nylon crown, 100% polyester mesh vents
• Weight: 2.6 ounces
• Key Feature: Sunglass Lock sleeves to keep eyewear secure

When using this hat, utilize the adjustable sizing cord at the back of the crown to get a snug, wind-resistant fit. The brim is designed to fold in half for easy packing, but avoid crushing the neck cape creases during long-term storage to maintain its structure. Keep the chin strap tucked back when not in high winds to prevent it from swinging and distracting your paddle stroke.

This hat is perfect for paddlers who prioritize maximum skin protection and lightweight comfort over traditional style. It is not the right choice for those who want a casual look for the post-paddle brewery, as its aesthetic is unapologetically utilitarian.

Sun Hoodie – Patagonia Tropic Comfort Natural Hoody

A sun hoodie is the core of any water-based sun protection system, shielding your torso, arms, and head without the need for greasy lotion. On a paddleboard, you need a garment that moves freely with your paddle stroke and does not cling to your skin when damp.

The Patagonia Tropic Comfort Natural Hoody stands out because of its incredibly soft, breathable modal-rayon and spandex blend. This fabric feels cool against warm skin, stretches easily during torso rotation, and features a generous hood designed to fit comfortably over a baseball cap or sun hat. The built-in thumb loops keep the sleeves pulled down to protect the backs of your hands.

• Fabric: 96% modal sun fabric, 4% spandex jersey
• UPF Rating: 40+ sun protection
• Fit: Relaxed trail-to-water fit
• Key Detail: Anti-odor HeiQ Pure treatment
• Weight: 8.3 ounces

Note that this fabric is designed for active airflow; it fits slightly loose to promote cooling currents of wind. While it dries incredibly fast, it does hold slightly more moisture initially than pure polyester, which actually assists in evaporative cooling on exceptionally hot days. Always rinse it in fresh water after saltwater paddles to prevent salt crystals from stiffening the fibers.

This hoodie is ideal for hot-weather paddlers who struggle with the plastic feel of traditional polyester rashguards. It is not suitable for cold-water sessions where an insulating neoprene top or a fully windproof layer is required.

Paddling Pants – NRS Silkweight Varial Pants

Legs are often overlooked on paddleboarding trips, yet they bear the brunt of reflected glare from the board’s deck. If you sit, kneel, or stand, your thighs and calves are constantly exposed to direct and bounced UV rays. Paddling pants provide full-leg defense while preventing deck-grip abrasion on your knees.

The NRS Silkweight Varial Pants are engineered specifically for paddlesports, utilizing an incredibly light, breathable nylon-spandex blend. They feature integrated stirrups that slide under your feet, preventing the cuffs from riding up your shins while you paddle or walk through the shallows. The side zippered pockets keep small essentials secure while sitting down.

• Material: 85% recycled polyester, 15% spandex (Silkweight fabric)
• UPF Rating: 50+ protection
• Features: Ankle stirrups, friction-free flatlock seams
• Sizing: Relaxed fit with a wide, comfortable waistband
• Storage: Secure zippered side pocket

These pants fit more loosely than traditional compression tights, allowing excellent air circulation. The waistband is wide and sits flat, meaning it will not dig into your stomach or chafe under a personal flotation device (PFD). If you are between sizes, size down for a sleeker fit that will not drag in the water during an accidental swim.

These are a must-have for paddlers who alternate between kneeling and standing, or those prone to sunburning their thighs. They are not recommended for those who prefer baggy, heavy cargo shorts, as loose, wet cotton fabric can cause severe inner-thigh chafing.

Paddling Gloves – Glacier Glove Ascension Bay Gloves

The backs of your hands are constantly exposed to the sky, receiving direct sunlight with every single paddle stroke. At the same time, friction from wet paddle shafts can quickly cause painful blisters that cut a trip short. Paddling gloves solve both problems, acting as a shield against friction and UV rays.

The Glacier Glove Ascension Bay Gloves are designed with a 4-way stretch synthetic material on the back that provides UPF 50+ protection. The palms feature a durable, high-grip synthetic leather that maintains its hold even when soaking wet, giving you better paddle control. The fingerless design ensures you retain the dexterity needed to adjust gear, open dry bags, or use your phone.

• Back Material: UPF 50+ 4-way stretch Lycra
• Palm Material: Durable synthetic leather with grip overlay
• Design: Fingerless cut for maximum tactile feedback
• Closure: Hook-and-loop wrist strap
• Weight: Lightweight and quick-drying

Ensure you get a tight, snug fit to prevent the fabric from bunching up in the palm, which can actually cause blisters rather than prevent them. Over time, the synthetic leather will stiffen if allowed to dry with saltwater or lake grime on it. Always rinse them in fresh water and air-dry them flat after every excursion.

These gloves are perfect for long-distance touring paddlers who want to protect their hands from blisters and sunspots. They are not designed for cold-water paddling, as they offer zero thermal insulation.

Why Loose-Fitting UPF Apparel Keeps You Cooler on the Water

It is a common misconception that tight, skin-hugging rashguards are the best option for hot days on the water. While compression gear works well for active surfing, it traps body heat and sweat directly against the skin. Loose-fitting UPF apparel, on the other hand, creates a microclimate that facilitates natural cooling.

When fabric sits slightly off the skin, it allows ambient wind to circulate beneath the garment. This airflow accelerates sweat evaporation, which is the body’s primary mechanism for dumping excess heat. When you move or paddle, the pumping action of the fabric acts like a bellows, actively pushing hot air out and pulling cooler air in.

Additionally, loose garments prevent the physical discomfort of chafing. Repetitive motions like paddling can cause tight, wet seams to rub raw spots under your arms and around your waist. A slightly relaxed drape ensures the fabric glides smoothly over your skin, keeping you comfortable for hours on end.

Polarized Sunglasses – Costa Del Mar Fantail PRO

Glare bouncing off the water does more than make you squint; it causes severe eye strain, headaches, and can damage your retinas over time. On a paddleboard, high-quality eyewear is also a safety tool, allowing you to see through the surface to identify shallow rocks, shoals, and underwater hazards.

The Costa Del Mar Fantail PRO sunglasses are built specifically for harsh marine environments. They feature Costa’s premium 580G color-enhancing glass lenses, which filter out harsh yellow light while blocking 100% of UV rays. The PRO frame includes side shields to block peripheral light, sweat channels to keep your vision clear, and non-slip Hydrolite nose and temple pads.

• Lens Material: 580G Lightwave Glass (highly scratch-resistant and ultra-clear)
• Frame Fit: Medium-large wrap-around
• Polarization: High-efficiency linear polarization
• Frame Features: Venting ports, sweat drains, side hoods
• Lens Tint Options: Blue mirror (deep water) or Green mirror (inland/flats)

While glass lenses offer unmatched clarity and scratch resistance, they are slightly heavier than polycarbonate alternatives. To prevent a catastrophic loss, always pair these sunglasses with a high-quality floating retainer strap. Clean the lenses only with a clean microfiber cloth to preserve the specialized outer coatings.

These sunglasses are ideal for serious paddlers who spend full days on bright, open water and require absolute visual clarity. They are not the best fit for casual paddlers looking for a budget-friendly option they don’t mind throwing into a beach bag unprotected.

Neck Gaiter – Buff CoolNet UV Neck Gaiter

The gap between your sun hat and your shirt collar is highly vulnerable to sunburn, especially on the back of the neck and the underside of the chin. A neck gaiter provides seamless, adjustable coverage for this sensitive area. It can easily be pulled up over your ears and nose when wind and glare intensify.

The Buff CoolNet UV Neck Gaiter is a versatile accessory for any outdoor kit. Made from lightweight, recycled polyester, it features built-in UPF 50+ protection and HeiQ cooling technology that triggers when it senses body heat. It stretches in four directions, staying securely in place without feeling restrictive or choking.

• Material: 95% recycled polyester, 5% elastane
• UPF Rating: 50+ certified
• Cooling Tech: HeiQ Smart Temp evaporative cooling
• Dimensions: One size fits most adults
• Eco-Friendly: Made from recycled plastic bottles

To maximize its cooling effect, dunk the Buff directly into the water and wring it out before putting it on. As the breeze hits the wet fabric, it creates an intense cooling sensation against your neck. Be sure to pull it up over your nose carefully so it does not fog up your sunglasses.

This is an essential accessory for anyone paddling in high-exposure saltwater or desert lake environments. It may not be comfortable for individuals who feel restricted or claustrophobic wearing fabric around their neck or face.

Water Shoes – Astral Loyak Water Shoes

Paddleboarding often involves launching from rocky shores, walking through muddy shallows, or portaging over rough terrain. Your feet need protection from sharp rocks, hot board surfaces, and direct UV rays on the instep. A secure water shoe ensures you can transition from land to water without slipping or injuring yourself.

The Astral Loyak Water Shoes offer the perfect balance of a low-profile board feel and robust sole protection. The outsoles are made of G.15 high-friction rubber, which grips wet rocks and slippery paddleboards with incredible tenacity. The canvas uppers are highly durable, dry quickly, and feature built-in drainage holes at the toe and heel.

• Outsole: G.15 high-friction, non-marking rubber (0.11 inches thick)
• Upper Material: Hydrophobic canvas with stretch mesh tongue
• Weight: 6.17 ounces per shoe
• Fit: True to size, flexible barefoot feel
• Closure: Lace-up for secure ankle retention

These shoes are designed to be worn without socks, so ensure you break them in on a few short trips before embarking on a multi-hour excursion. The flexible, thin sole is excellent for feeling the board underfoot, but it does not provide heavy arch support for long overland hikes. Rinse them inside and out with fresh water after use to clear out any trapped sand or silt.

These shoes are perfect for paddlers who need a secure, high-grip shoe that transitions seamlessly from wet launches to standing on the board. They are not the right choice for paddlers looking for heavy-duty, stiff hiking boots for extensive portaging.

Wind Shell – Patagonia Houdini Jacket

Even on hot summer days, weather on open water can change rapidly. A sudden wind shift or an unexpected afternoon squall can cause a rapid drop in ambient temperature. When you are wet, even a moderate breeze can lead to rapid evaporative cooling, leaving you shivering and exhausted.

The Patagonia Houdini Jacket is the ultimate insurance policy for any paddleboarding excursion. Weighing a mere 3.7 ounces, this wind shell blocks biting drafts and sheds light spray thanks to its durable water repellent (DWR) finish. It packs down into its own zippered chest pocket, making it small enough to clip to a PFD or slide into a dry bag.

• Weight: 3.7 ounces (105 grams)
• Material: 1.2-ounce 100% recycled nylon ripstop
• Weather Resistance: DWR (durable water repellent) finish
• Packability: Stuffs into its own chest pocket with a carabiner clip loop
• Fit: Slim fit with drop-tail hem for lower back coverage

The Houdini has a slim fit, so if you plan to wear it over a bulky PFD or a loose sun hoodie, consider sizing up. Because the nylon fabric does not stretch, a larger size also ensures you maintain full mobility for paddling strokes. Keep in mind that this is a highly breathable wind shell, not a heavy, fully waterproof rain slicker.

This jacket is a must-have safety layer for any paddler heading out on large, unpredictable bodies of water. It is not suitable for those looking for a heavy, rubberized raincoat designed to withstand hours of torrential downpours.

How to Maintain and Wash Your UPF Technical Clothing

The sun-protective capabilities of technical clothing rely on dense fabric weaves, specialized fibers, or UV-absorbing treatments. Over time, salt, sand, body oils, and chlorine can clog these fibers and degrade the UPF protection. Proper maintenance is essential to ensure your gear continues to shield you effectively season after season.

Always rinse your UPF apparel in cool, fresh water immediately after your paddle trip to flush out salt and sediment. When washing, use a mild, liquid detergent on a gentle cycle, and avoid fabric softeners at all costs. Softeners coat the fibers with a waxy residue that destroys the fabric’s breathability, moisture-wicking properties, and cooling capabilities.

Hang-drying your technical clothing in the shade is always the preferred method. While some UPF garments can handle a low-heat tumble dry, excessive heat from a dryer can break down spandex and elastic fibers, causing the gear to lose its shape and sun-blocking density.

Staying Hydrated and Managing Heat on Full-Day Paddle Trips

Sun-protective clothing works wonders, but it is only half of the thermal regulation equation on a full-day paddle. The combination of direct heat, exertion, and wind creates a rapid evaporation rate that can mask how much you are actually sweating. By the time you feel thirsty, you are already entering the early stages of dehydration.

To maintain your stamina, carry a hands-free hydration bladder mounted to your PFD or secured on your board’s deck lines. Sipping small amounts of water every 15 minutes is vastly superior to chugging a full bottle once an hour. On hot days, supplement your water with electrolyte tablets to replace the essential salts lost through sweat.

Monitor your body for early signs of heat fatigue, such as a mild headache, dizziness, or a sudden drop in paddling efficiency. If you feel overheated, splash water onto your wet neck gaiter and sleeves to utilize the immediate cooling effects of evaporation. Pace yourself, take regular breaks in shaded shoreline areas, and let the wind work with your technical apparel to keep your core temperature stable.

Equipping yourself with the right sun-protective gear transforms a long day on the water from an endurance test into a pure pleasure cruise. By selecting high-quality UPF clothing and understanding how to manage your thermal output, you can paddle with absolute confidence. Focus on the water ahead, stay protected, and enjoy every mile of your journey.
