Castelli

UPF 50 + Light Knee 3 Sleeves

What Our Gearhead® Experts Are Saying:

"Perfect for sunny rides where you want extra coverage but not the weight of thermal warmers. These breathe super well and actually stay in place all ride—no slipping, no overheating, just simple sun protection."

The Castelli UPF 50+ Light Knee 3 Sleeves are built for cyclists who train and ride in full sun but want to avoid the hassle—and reapplication—of sunscreen. Featuring Castelli’s lightweight Solare fabric, these sleeves offer UPF 50+ protection with breathable, moisture-wicking performance that keeps you dry and cool, even on long, hot climbs.

The polyester-based construction helps rapidly pull sweat away from the skin while maintaining a soft, non-restrictive feel. A silicone elastic gripper at the top hem ensures the sleeves stay firmly in place without digging in, bunching, or sliding mid-ride. The streamlined cut fits easily under your favorite bibs, providing reliable sun protection with minimal bulk.

Designed for long miles in sunny climates or high-altitude exposure, the UPF 50+ Light Knee 3 Sleeves are a smart, comfortable solution for those who ride hard and stay out long.
