Stay protected, comfortable, and focused on every ride with the Castelli UPF 50+ Arm Sleeves (White). Designed for cyclists who train and compete in demanding weather conditions, these premium arm sleeves combine advanced UV protection, lightweight performance fabrics, and Castelli's race-inspired engineering to deliver exceptional comfort and functionality. Whether you're riding under intense summer sunshine, tackling long endurance events, participating in gran fondos, or enjoying daily training sessions, these arm sleeves provide the protection and performance needed for every kilometer.
Crafted from high-quality stretch performance fabric, the Castelli UPF 50+ Arm Sleeves offer a close anatomical fit that feels like a second skin. The four-way stretch material moves naturally with your arms, ensuring unrestricted mobility while maintaining gentle muscle support. Their ergonomic construction is specifically designed to remain comfortable in the cycling position, eliminating excess fabric and reducing distractions during long hours in the saddle.
One of the key features of these arm sleeves is their UPF 50+ sun protection, providing one of the highest levels of defense against harmful ultraviolet radiation. By blocking more than 98% of UVA and UVB rays, they help protect exposed skin from sunburn and reduce long-term damage caused by prolonged sun exposure. This makes them an ideal choice for summer road rides, endurance races, mountain climbs, gravel adventures, triathlons, and high-altitude cycling where UV intensity is significantly greater.
The advanced moisture-wicking fabric rapidly transports perspiration away from the skin, allowing sweat to evaporate quickly and helping maintain a cool, dry, and comfortable riding experience. The highly breathable construction promotes continuous airflow, preventing heat buildup even during intense efforts. As your body temperature rises, the fabric works efficiently to regulate moisture, helping you remain comfortable throughout changing weather conditions.
The White colorway offers additional cooling benefits by reflecting sunlight rather than absorbing it, helping reduce heat accumulation during rides in direct sun. This reflective property makes the sleeves particularly effective for hot-weather cycling, allowing riders to stay cooler without sacrificing protection.
Designed with long-distance comfort in mind, the Castelli UPF 50+ Arm Sleeves feature wide elastic cuffs with integrated silicone grippers that securely hold the sleeves in position without creating pressure points. Whether you're climbing steep gradients, sprinting to the finish, or maintaining an aerodynamic posture for hours, the sleeves stay comfortably in place without slipping or bunching.
Flatlock seam construction minimizes friction against the skin and significantly reduces the risk of irritation or chafing during extended rides. The premium stitching also enhances durability, allowing the sleeves to maintain their shape, elasticity, and performance even after repeated washing and regular use throughout the cycling season.
These versatile arm sleeves are far more than just sun protection. They provide an extra layer of comfort during cool morning starts, offer light insulation on breezy descents, and can easily be removed and stored in a jersey pocket as temperatures rise. Their compact design makes them an essential accessory for riders who frequently encounter changing weather conditions during long rides.
Perfect for road cycling, gravel riding, mountain biking, endurance racing, triathlon, bikepacking, touring, commuting, and recreational cycling, the Castelli UPF 50+ Arm Sleeves adapt effortlessly to a variety of disciplines and riding styles. Their lightweight construction ensures they integrate seamlessly with any cycling jersey without adding unnecessary bulk.
Backed by Castelli's decades of innovation and trusted by professional cyclists around the world, these arm sleeves reflect the brand's commitment to combining cutting-edge performance with premium comfort. Every detail has been engineered to help cyclists perform at their best while staying protected from the elements.
Whether you're training through the hottest months of the year, preparing for your next race, or simply enjoying long days on the bike, the Castelli UPF 50+ Arm Sleeves (White) deliver professional-level sun protection, breathable comfort, and reliable performance. Lightweight, durable, and easy to carry, they are an indispensable addition to any cyclist's wardrobe, ensuring you're ready for every ride, every season, and every challenge.
