What Our Gearhead(R) Experts Are Saying:"I use the UPF 50+ Light Leg Sleeves for long summer base rides. They give me peace of mind on exposed routes without trapping heat like traditional leg warmers. The silicone grip keeps them up, and they wick really well-surprisingly comfortable even when it's blazing."Big days in the saddle often mean big exposure, and that's when we turn to the Castelli UPF 50+ Light Leg 3 Sleeves. Offering full-leg sun coverage without adding weight or warmth, these sleeves are built to keep us cool, protected, and riding longer under bluebird skies. Crafted from lightweight Solare fabric, they deliver UPF 50+ protection and excellent moisture management. The polyester construction pulls sweat away quickly, while silicone elastic at the thigh holds everything securely in place without pinching. When sunscreen alone won't cut it, these sleeves are our go-to for high-mileage, sun-drenched rides.
