9 UV-Rated Sailing Gear for High Exposure Days

The glare off the water on a cloudless afternoon can turn a perfect day of sailing into a brutal battle with sunburn and dehydration before the afternoon breeze even fills in. When you are miles from the nearest shade on an open deck, standard beachwear simply cannot handle the relentless assault of direct and reflected ultraviolet rays. Investing in purpose-built, UV-rated marine gear is the ultimate way to stay comfortable, protected, and focused on trimming your sails.

Understanding UV Risks and Marine Sun Protection

Spending a day on deck means facing a double dose of solar radiation. Sunlight hits your skin directly from above, but it also bounces off the water’s surface, the white fiberglass deck, and even your sails, intensifying your overall UV exposure. This multi-directional assault makes standard cotton clothing virtually useless once it gets damp with sweat or salt spray.

True marine sun protection relies on Ultraviolet Protection Factor (UPF) ratings, which measure how much UV radiation penetrates a fabric. Unlike standard clothing, which might let up to 20% of UV rays through, high-quality sailing apparel blocks up to 98% of harmful radiation. Understanding how these fabrics interact with salt, wind, and constant movement is the first step toward safeguarding your health on the water.

Sailing Shirt – Gill UV Tec Hooded Long Sleeve

A dedicated sailing shirt acts as your primary shield against the midday sun, eliminating the need to constantly reapply greasy sunscreen to your arms and torso. The Gill UV Tec Hooded Long Sleeve is engineered specifically for active deck work, offering UPF 50+ protection in a lightweight, breathable package. It excels at transferring moisture away from the skin, ensuring you stay cool even when grinding winches in dead calm conditions.

What sets this shirt apart is its thoughtfully designed hood, which fits comfortably under a cap or safety helmet without obstructing peripheral vision. The ultra-lightweight technical fabric dries in minutes after taking a rogue wave over the bow, while the flatlocked seams prevent chafing during repetitive motions. Key specifications include:

• Fabric: 100% Polyester technical knit
• Sun Protection: UPF 50+
• Fit: Relaxed but functional athletic cut
• Key Feature: Thumb loops to keep sleeves securely in place

Keep in mind that this shirt is designed with a slightly tailored cut to prevent excess fabric from catching on blocks or rigging. If you prefer a loose, baggy fit for casual lounging on the dock, consider sizing up. This garment is perfect for active helmsmen and crew members who need maximum mobility, but it might feel too technical for someone looking for a simple, loose beach cover-up.

Sailing Pants – Musto Evolution Performance 2.0

Bare legs on a sailboat are an open invitation for sun damage, non-skid scrapes, and painful salt-crust chafing. The Musto Evolution Performance 2.0 sailing pants solve this by combining high-level sun protection with heavy-duty durability. These pants are designed to withstand the abrasive nature of textured decks while shielding your skin from overhead and reflected light.

Built with UPF 40 stretch fabric, these pants allow for a full range of motion whether you are crouching in the cockpit or climbing onto the foredeck. They feature reinforced Schoeller-keprotec patches on the seat and knees to prevent wear and tear from constant sitting and kneeling on rough surfaces. Key details:

• Material: Fast-dry polyamide fabric with 4-way stretch
• Reinforcement: Keprotec patches for ultimate durability
• Sun Rating: UPF 40
• Storage: Multiple cargo and secure zip pockets

Note that Musto uses UK/European sizing, which tends to run smaller and more tailored than standard US sizing, so checking the size chart carefully before buying is essential. These pants are a must-have for sailors who actively move around the boat and need rugged protection, but they may be overkill for a casual lake boater who spends most of their time sitting quietly under a bimini.

Sun Hat – Tilley LTM6 Airflo Broad Brim Hat

A wide-brimmed hat is non-negotiable for protecting your face, ears, and back of the neck from direct vertical rays. The Tilley LTM6 Airflo Broad Brim Hat is the gold standard for watermen because it combines reliable UPF 50+ sun protection with a design that refuses to sink or fly away. Its wide brim provides consistent shade without blocking your line of sight when looking up at the masthead fly.

The Airflo mesh band around the crown allows heat to escape, keeping your head cool on windless, humid days. It is constructed from a lightweight, water-repellent nylon fabric and features a dual-strap wind cord system that keeps the hat secured to your head in stiff breezes. Bullet points:

• Brim Size: Front & Back: 3 1/2″, Sides: 2 1/2″
• Material: 100% Supplex nylon with Tilley mesh
• Flotation: Closed-cell foam in the crown ensures it floats
• Protection: Certified UPF 50+

Tilley hats require precise sizing measurements rather than generic “one-size-fits-all” adjustments to ensure the wind cords work effectively without causing pressure headaches. While this hat is virtually indestructible and perfect for long days on open water, those who prioritize low-profile, aerodynamic headwear for high-speed racing may find the broad brim too bulky in heavy winds.

Sailing Gloves – Gill Deckhand Gloves Long Finger

Hands are incredibly vulnerable on a boat, constantly exposed to harsh sunlight on the steering wheel or tiller, alongside the physical abuse of handling sheets and halyards. Gill Deckhand Gloves (Long Finger) protect the sensitive skin on the backs of your hands from UV damage while preventing painful rope burns. Leaving only the tips of your thumb and index finger exposed ensures you retain the dexterity needed for tying knots and handling small hardware.

These gloves feature a UPF 50+ main fabric on the back of the hand and a double-layer Amara leather reinforcement on the palm for excellent grip and durability. The offset wrist closures prevent watch interference, allowing you to easily check your race timer or GPS. Specifications:

• Material: Amara synthetic leather palm and UV-treated back fabric
• Design: “Long finger” style (tips of thumb and index finger open)
• Closure: Secure hook-and-loop wrap-around wristband
• Protection: UPF 50+ on non-leather panels

Because synthetic leather shrinks slightly after repeated wet-dry cycles, it is wise to buy a pair that feels slightly roomy out of the package. These gloves are indispensable for anyone actively trimming sails or helming for hours, but casual passengers who do not handle lines may find them unnecessary.

Polarized Sunglasses – Costa Del Mar Fantail PRO

Reflected glare off the water’s surface can cause eye fatigue and long-term UV damage, while obscuring shallow hazards and wind shifts. The Costa Del Mar Fantail PRO polarized sunglasses are built to eliminate this glare, using advanced lens technology to clarify your field of view. These glasses provide a crucial barrier against wind, salt spray, and harmful UVA/UVB rays.

Equipped with Costa’s proprietary 580G light-blocking glass lenses, these sunglasses filter out harsh yellow light while enhancing reds, greens, and blues for unmatched visual definition. The PRO frame includes side shields to block peripheral light, sweat channels to prevent fogging, and Hydrolite rubber grips to keep the glasses glued to your face during sudden maneuvers. Key details:

• Lens Material: Scratch-resistant 580G Lightwave Glass
• Frame Features: Hydrolite nose and temple pads, side shields
• Polarization: 100% UV protection and high-efficiency polarization
• Recommended Lens: Blue Mirror for bright, open-water sailing

Glass lenses offer the absolute best clarity and scratch resistance, but they are heavier than plastic alternatives and can shatter if dropped on a hard fiberglass deck. This premium eyewear is ideal for helmsmen and navigators who need precise visual feedback, but a retainer strap is highly recommended to keep this investment from slipping into the depths.

Neck Gaiter – Buff CoolNet UV Multifunctional

The area between your collar and your hat brim is highly susceptible to severe sunburn due to light bouncing directly up from the water and white deck surfaces. A Buff CoolNet UV Multifunctional neck gaiter seals this vulnerability, offering seamless protection that can be worn in multiple configurations. Whether pulled up over your ears and nose or worn loosely around your neck, it acts as a reliable physical barrier against the sun.

Crafted from lightweight, recycled polyester, this gaiter features Heiq cooling technology that activates when wet, helping to lower your skin temperature on sweltering days. The 4-way seamless stretch construction ensures there are no rough edges to chafe your skin when turning your head to watch the sails. Bullet points:

• Material: 95% Recycled polyester, 5% Elastane
• Protection: UPF 50+ certified
• Cooling: HeiQ Smart Temp evaporative cooling technology
• Construction: 100% seamless tube design

While highly breathable, wearing a neck gaiter over your nose can sometimes cause sunglasses to fog up if not positioned correctly. This accessory is a game-changer for long days in intense heat, but individuals who feel claustrophobic with fabric over their face might prefer to rely strictly on wide-brimmed hats and high-collar shirts.

Technical Sailing Cap – Zhik UV Active Cap

On high-wind days when a broad-brimmed hat would easily catch the breeze and fly overboard, a technical sailing cap becomes your go-to headwear. The Zhik UV Active Cap offers a streamlined, aerodynamic fit designed to stay put when the wind pipes up. It provides excellent forehead and eye shade while remaining incredibly lightweight and unobtrusive.

Made from high-performance fabric with UPF 50+ sun protection, this cap is designed to shed water and dry almost instantly. It features a secure, adjustable rear strap and a built-in retainer clip to attach the cap to your shirt collar, ensuring it won’t be lost to a sudden gust. Specifications:

• Material: Fast-drying performance polyester
• Sun Rating: UPF 50+
• Retention: Integrated collar clip and adjustable strap
• Ventilation: Laser-cut side vents for airflow

Because a baseball-style cap leaves your ears and the back of your neck completely exposed, it must be paired with a neck gaiter or hooded sun shirt for comprehensive protection. This cap is perfect for active racing sailors who need low-profile headwear that stays secure during fast maneuvers, but it is less suited for leisurely days on calm waters where maximum shade is preferred.

Deck Shoes – Sperry Sea Kite Sport Moc Boat Shoe

Bare feet on a hot fiberglass deck are prime targets for painful sunburn, stubbed toes on deck hardware, and dangerous slips. The Sperry Sea Kite Sport Moc Boat Shoe provides the ultimate platform for deck safety, keeping your feet shielded from direct UV rays while ensuring stable footing on wet, pitching surfaces. Unlike traditional leather loafers, this athletic-style boat shoe is built for active performance on open water.

Featuring water-resistant leather and mesh uppers, these shoes dry rapidly and use Adaptive Wave-Siping on the outsoles to disperse water underfoot, preventing hydroplaning on slick decks. The removable compression-molded EVA footbed provides lasting cushion and comfort for long hours standing at the helm. Key details:

• Outsole: Non-marking rubber with Adaptive Wave-Siping
• Upper: Water-resistant leather and mesh panels
• Lining: Moisture-wicking mesh with antimicrobial treatment
• Closure: Secure 360-degree lacing system

To maintain their grip and prevent mold, these shoes should be rinsed with fresh water and allowed to dry completely in the shade after exposure to salt water. This high-traction shoe is ideal for active crew members navigating slippery decks, though casual sailors who stay securely inside a protected cockpit might find lighter mesh slip-ons sufficient.

Marine Sunscreen – Thinksport SPF 50+ Mineral

No matter how comprehensive your technical clothing is, there will always be exposed areas like your face, ears, and hands that require chemical-free barrier protection. Thinksport SPF 50+ Mineral Sunscreen offers a highly effective physical shield against both UVA and UVB rays without introducing harmful chemicals to fragile marine ecosystems. This zinc oxide-based formula stays put through heavy sweating and salt spray, providing reliable safety where fabrics cannot cover.

Unlike chemical sunscreens that degrade in sunlight and can damage coral reefs, this mineral formula is biodegradable and reef-friendly, meeting the highest standards for environmental safety. It provides up to 80 minutes of water resistance, making it highly durable against the splashing and sweating common in active sailing. Bullet points:

• Active Ingredient: 20% Non-nano Zinc Oxide
• Sun Protection: SPF 50+ Broad Spectrum
• Water Resistance: FDA-rated for 80 minutes
• Environmental: Leaping Bunny certified cruelty-free and reef-safe

Because zinc oxide is a physical blocker, it goes on thick and white, requiring thorough rubbing to blend into the skin. While this ensures you do not miss any spots, it can leave a white residue on dark fabrics or leather boat upholstery if you rub against them before the lotion dries. This is an essential safety item for any water recreationalist, though those who refuse to use mineral-based lotions due to the white cast may need to search for clear chemical alternatives (though these are less environmentally friendly).

How to Wash and Care for Your UV-Rated Sailing Gear

High-performance sailing gear relies on specialized weaves and chemical treatments to maintain its UPF rating. Over time, salt crystals, body oils, and dried sunscreen can clog the microfibers of technical apparel, reducing both breathability and sun protection. Proper care is essential to ensure your expensive gear continues to perform season after season.

After every outing, rinse your UV clothing in cold, fresh water to wash away abrasive salt and sweat. When machine washing, use a mild liquid detergent and completely avoid fabric softeners or dryer sheets. Softeners leave a waxy coating on synthetic fibers that clogs the pores, destroying the fabric’s moisture-wicking capabilities and degrading the built-in UV protection.

Always hang-dry your technical clothing in the shade rather than throwing it in a hot dryer. High heat can break down the elastane and spandex fibers that give sailing pants and shirts their comfortable stretch, leading to sagging and premature wear. Taking these simple steps will preserve the UPF rating and structural integrity of your gear for years.

How to Choose the Right UPF Rating for Open Water

Navigating the technical specifications of sun-protective clothing can be confusing, but understanding the UPF scale is critical for open-water safety. UPF measures how much UVA and UVB radiation a fabric blocks. For example, a shirt with a UPF 15 rating allows 1/15th (roughly 6.7%) of UV radiation to pass through, which is adequate for casual shade but insufficient for long days on an open deck.

For high-exposure days on open water, you should exclusively look for gear rated UPF 50+, which blocks 98% or more of harmful rays. At this level, the fabric provides “Excellent” protection, significantly reducing the risk of deep cellular skin damage. Because water reflects up to 20% of UV radiation back upward, anything less than UPF 40 will quickly leave you vulnerable to burns on a clear summer day.

Consider the weave and weight of the fabric when making your selection. A tight, dense weave naturally blocks more light but can trap heat if it lacks advanced cooling technology. Look for fabrics that achieve their UPF rating through mechanical weave rather than chemical washes alone, as mechanical protection will not wash out over time.

Conclusion

Equipping yourself with the right UV-rated gear transforms a potentially exhausting day of sun exposure into a comfortable, safe adventure on the water. By selecting high-quality fabrics, functional designs, and reef-safe skin protection, you can confidently handle whatever conditions the open water throws your way. Pack your gear, check the wind forecast, and enjoy your time on deck with total peace of mind.
