Unisex, Warmer

The Castelli Light Leg Skins are designed for protecting riders' skin from the sun's harmful rays during summer riding. Featuring a lightweight polyester base fabric, the Light Leg Skins quickly and efficiently wick moisture way.

We can officially only rate these warmers at UPF 50+, but in our laboratory tests they actually blocked 99.8 percent of damaging UV rays. We used a polyester base that is not only more effective than nylon at blocking UV rays but is also much better at keeping you dry, which means these arm sleeves are better in both cooler and warmer conditions.
