Castelli UPF 50+ Light Road Arm Sleeves Black

The Castelli UPF 50+ Light Arm Sleeves were made using 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. Castelli kept the construction very clean to eliminate seams that can rub, and they used a double-sided silicone elastic to make sure they stay in place. They fold up extremely small, so they’re great to stick in your pockets for your next big mountain day.WHAT IT ISFor maximum sun protection with minimal insulation.Castelli UPF 50+ Light Arm Sleeves FeaturesSolare fabric keeps the chill off without causing overheatingUPF 50+ protectionPolyester based for excellent moisture managementDouble-side silicone elastic at top for excellent grip12°-35°C / 53°-95°FWeight:67g
