9 UV-Rated Gear for Sailing Crew on Hot Summer Days

Mid-July on a recreational sailboat brings the perfect mix of steady wind and clear skies, but the open water also acts as a giant mirror for harsh solar radiation. Spending hours on deck without proper defense can quickly turn a glorious day of cruising into a painful ordeal of sunburn and heat exhaustion. Equipping yourself and your crew with the right UV-rated gear is the single best way to stay comfortable, sharp, and safe during long summer runs.

Why UV Protection Matters on the Open Water

Sailing exposes you to a double dose of solar radiation. Sunlight hits you directly from above, but it also reflects off the water’s surface, sails, and fiberglass decks, intensifying your UV exposure by up to 25 percent. On a boat, there is rarely any natural shade, meaning your skin and eyes are under constant assault from the moment you cast off.

Sun damage on the water happens faster than it does on land, and wind cooling can mask the sensation of burning until it is too late. Overexposure leads to rapid dehydration, fatigue, and impaired decision-making—dangerous variables when managing rigging or navigating a busy channel. Quality UPF (Ultraviolet Protection Factor) gear acts as a physical barrier that doesn’t wash off with sweat or spray, keeping the crew cool and focused on the task at hand.

Sun Hoodie – Patagonia Capilene Cool Daily Hoody

A dedicated sun hoodie is the modern sailor’s primary shield against intense UV rays, replacing heavy cotton shirts that trap moisture. This layer must breathe, block the sun, and dry almost instantly when sprayed by a bow wave. The Patagonia Capilene Cool Daily Hoody excels at this by using a lightweight 100% recycled polyester fabric that feels cool against the skin even in dead-calm conditions.

What sets this hoody apart is its miDori bioSoft treatment for added softness and moisture-wicking capability, paired with HeiQ Pure odor control. The hood is designed to fit comfortably over a sailing cap without obstructing peripheral vision, a crucial detail when watching for wind shifts or keeping an eye on the boom.

Keep in mind that this hoody features a relaxed fit; if you prefer a streamlined fit that won’t snag on blocks and lines, consider sizing down. It is ideal for active deckhands who need maximum mobility and dependable UPF 50+ protection, but it might feel too casual for those who prefer traditional, collared sailing shirts.

• Fabric: 3.7-oz polyester jersey
• Sun Protection: UPF 50+ (on solid colors)
• Best For: Active crew work, hot-weather regattas, and light paddle sports

Sailing Hat – Tilley LTM6 Airflo Broad Brim Hat

A reliable sailing hat must protect your face, ears, and neck while staying firmly anchored to your head when the wind picks up. The Tilley LTM6 Airflo Broad Brim Hat is a marine classic because it combines robust sun blocking with structural integrity that prevents the brim from flopping into your eyes during high-wind tacks.

Built with a lightweight, water-repellent nylon, this hat features a 3/4-inch mesh ventilation strip around the crown to let hot air escape. The dual-wind cord system loops behind your head and under your chin, securing the hat in heavy gusts, while a closed-cell foam insert in the crown ensures it floats if it does end up in the drink.

Tilley hats require precise sizing rather than a one-size-fits-all strap, so measure your head carefully before buying—a fit that is too tight will cause headaches on long, hot days. This hat is perfect for helmsmen and cruisers who need maximum coverage, though active foredeck crews might find the wide brim occasionally interferes with low-clearance rigging.

• Material: 100% supplex nylon
• Brim Width: Front & Back: 3 1/2″, Sides: 2 1/2″
• Key Feature: Floats on water and includes a hidden pocket

Polarized Sunglasses – Costa Del Mar Fantail PRO

Sunglasses on a sailboat are not a fashion statement; they are critical safety gear. Glare off the water strains the eyes, hides shallow sandbars, and obscures wind ripples on the surface. The Costa Del Mar Fantail PRO uses polarized glass lenses that filter out yellow light, drastically improving contrast and allowing you to read the water with absolute clarity.

The “PRO” designation means these frames feature side shields to block peripheral light, hooding to prevent overhead glare, and hydrolite nose and temple pads that grip tighter as you sweat. The durable bio-resin frames are built to survive the bumps and drops common in a chaotic cockpit.

These glasses are a premium investment, and pairing them with a floating retainer strap is non-negotiable to prevent them from sinking to the bottom. They are the ultimate choice for the helmsman or tactician who needs to spot wind shifts and obstacles, but casual passengers may find the high price tag unnecessary.

• Lens Material: 580G Polarized Glass
• Frame Fit: Regular/Medium
• Best For: High-glare marine environments and light navigation

Neck Gaiter – Buff CoolNet UV Half Multifunctional

The area right below your chin is highly vulnerable to reflected glare off the deck, making a neck gaiter an essential piece of summer sailing gear. It bridges the gap between your shirt collar and your hat. The Buff CoolNet UV Half Multifunctional offers a shorter, more manageable length than standard neck tubes, reducing bulk around your collar while still protecting critical areas.

Made from 95% recycled REPREVE microfiber, this gaiter features HeiQ cooling technology that triggers when you sweat to keep your neck temperature down. Its four-way stretch fabric fits snugly without restricting breathing or swallowing, and it stays dry even when subjected to heavy sea spray.

Because it is a half-length gaiter, it won’t pull up over your nose and ears as easily as a full Buff, so it is best paired with a wide-brimmed hat. This is a must-have for crew members who spend hours staring aloft or looking down at instruments, though those who suffer from claustrophobia in hot weather may prefer a loose collar instead.

• Material: 95% recycled polyester, 5% elastane
• Sun Protection: UPF 50+
• Key Feature: HEIQ cooling technology

Sailing Gloves – Gill Marine Deckhand Gloves

Active sailing means handling loaded sheets, halyards, and mooring lines, which can quickly shred soft skin or cause friction burns. While gloves are primarily for hand protection, they also shield the backs of your hands—a prime target for constant UV exposure. The Gill Marine Deckhand Gloves feature short-finger coverage that keeps your fingertips free for tying knots while shielding the rest of your hand.

These gloves are constructed with Amara fabric that does not absorb water and dries soft, avoiding the stiff, crusty feel of wet leather. The palm features a double-layer reinforcement for excellent grip on wet lines, while the back of the hand is built with a flexible, UV-protective fabric.

Ensure you check the sizing chart, as a glove that is too loose will bunch up and cause blisters, while a tight glove restricts blood flow. These are perfect for active trimmers and foredeck crew, but casual cruisers who rarely handle lines may find them unnecessary.

• Material: Amara synthetic leather and nylon stretch back
• Style: Short-finger
• Best For: Ropework, line handling, and hand UV protection

Marine Sunscreen – Thinksport SPF 50+ Sunscreen

Even with UPF clothing, exposed areas like your face, ears, and the back of your hands require high-quality topical protection. On a boat, you need a formula that won’t wash off with sweat or salt spray, and one that won’t harm the marine environment when you dive in. Thinksport SPF 50+ Sunscreen is a mineral-based sunscreen utilizing non-nano zinc oxide to create a physical block against both UVA and UVB rays.

This formula is highly water-resistant (rated for up to 80 minutes) and lacks the oily, greasy finish that can make hands slip on winches or steering wheels. Crucially for boaters, it is free of biologically harmful chemicals like oxybenzone and octinoxate, making it safe for sensitive marine ecosystems.

Because it is a mineral sunscreen, it goes on thick and requires thorough rubbing to avoid a white residue. It is essential for every person on board, though individuals who dislike the heavier feel of zinc-based lotions may need to apply it in smaller, well-blended increments.

• Active Ingredient: Zinc Oxide 20% (Non-nano)
• Water Resistance: 80 minutes
• Certification: Leaping Bunny certified cruelty-free and reef-friendly

Sailing Pants – Helly Hansen Crew Cargo Pants

Shorts might seem like the natural choice for hot days, but hours spent kneeling on non-skid decks or sitting on hot fiberglass will quickly change your mind. Sailing pants protect your legs from both scraping deck hardware and relentless sun exposure. The Helly Hansen Crew Cargo Pants are built from a lightweight, quick-dry canvas that provides physical protection without trapping heat.

These pants feature cargo pockets for storing small tools or rigging tape, and the articulated knees allow you to move freely when moving across the high side of the boat. The fabric is treated with a DWR (Durable Water Repellent) finish to shed light spray, and it offers excellent UPF protection.

The fit is tailored, meaning they won’t bag or catch on cleats, but you should verify your waist size as there is minimal stretch in the waistband. They are perfect for active crew members who need to move quickly on deck, while relaxed day-sailors might find lightweight shorts more comfortable for casual lounging.

• Material: 100% Polyamide quick-dry canvas
• Pockets: Cargo pockets, hand pockets, back pockets
• Fit: Straight-leg, active fit

UV Arm Sleeves – Outdoor Research ActiveIce Sleeves

If you prefer the comfort and classic look of a short-sleeve polo shirt but still need reliable sun protection during peak hours, arm sleeves are the perfect compromise. They are easy to slip on during the heat of the day and slide off when the sun goes down or when you head into the yacht club. The Outdoor Research ActiveIce Sleeves utilize a specialized fabric that actually lowers skin temperature as you sweat.

These sleeves feature a UPF 50+ rating and use an active cooling treatment that responds to moisture, making them feel cool even in humid conditions. Silicone grip prints at the bicep keep the sleeves from sliding down while you work winches or raise sails, and the thumbholes provide extended coverage over the back of your hands.

Pay attention to bicep sizing to ensure a secure fit that doesn’t pinch or cut off circulation. They are an excellent tool for versatile sailors who want customizable sun protection, but they are not ideal for those who prefer the all-in-one simplicity of a full sun hoodie.

• Fabric: 91% polyester, 9% spandex
• Sun Protection: UPF 50+
• Key Feature: Moisture-activated cooling and bicep grip strips

SPF Lip Balm – Sun Bum SPF 30 Mineral Lip Balm

The lips are one of the most commonly overlooked areas for sun protection, yet they are highly susceptible to painful windburn and UV damage on the water. Wind, salt, and sun work together to dry out and burn delicate lip tissue. Sun Bum SPF 30 Mineral Lip Balm provides a protective zinc oxide barrier that locks in moisture while shielding against radiation.

This zinc-based balm is formulated with shea butter and sweet almond oil to soothe chapped lips without leaving a waxy or sticky residue that attracts flying salt spray or sand. It is fragrance-free and hypoallergenic, ensuring it won’t irritate cracked skin during long days on the water.

Mineral lip balms can leave a slight white tint if applied too heavily, so a little goes a long way. This is an essential pocket item for every crew member on board, though those who prefer flavored or chemical sunscreens may find the unscented mineral texture takes some getting used to.

• Active Ingredients: Zinc Oxide 8%
• Sun Protection: SPF 30
• Key Ingredients: Shea butter, jojoba oil, and sweet almond oil

How to Wash and Maintain Your UPF Sailing Gear

UPF clothing relies on tight fabric weaves and specialized chemical treatments to block UV rays, both of which can degrade if washed incorrectly. Saltwater crystallization can clog the weave of technical fabrics, reducing their breathability and compromising their sun-blocking effectiveness. After every sail, rinse your gear in fresh water to dissolve salt deposits before throwing them in the wash.

Always wash your sailing gear in cold water on a gentle cycle, using a mild liquid detergent. Avoid fabric softeners at all costs; they coat the fibers with a waxy residue that ruins the fabric’s moisture-wicking and cooling properties. Hang-drying is highly recommended, as the high heat of a dryer can break down elastic fibers and shrink technical knits, altering the tight weave required for UPF performance.

Essential Heat Safety Tips for Summer Crews

No amount of UV-rated gear can fully protect you if you neglect basic hydration and body temperature management. Dehydration sets in rapidly on a boat due to the constant wind drying your sweat before you even realize you are perspiring. Establish a rule on board that everyone must drink water at regular intervals, prioritizing water or electrolyte-rich drinks over caffeinated or alcoholic beverages.

Learn to recognize the early signs of heat exhaustion among your crew, which include dizziness, headache, rapid pulse, and cool, clammy skin. If someone shows these signs, get them out of the direct sun immediately, apply cool, wet towels to their neck and underarms, and have them sip cool water. Keeping a well-stocked cooler with ice and extra fresh water is just as critical to boat safety as having life jackets on board.

Conclusion

Navigating hot summer days on the water is incredibly rewarding when you are equipped to handle the elements. Investing in high-quality, UV-rated gear keeps you cool, protects your skin, and ensures you have the stamina to handle whatever conditions the wind throws your way. Gear up properly, stay hydrated, and enjoy a safe, sunburn-free season on the open water.
