Castelli can officially only rate these arm sleeves at UPF 50+, but in their laboratory tests, these sleeves actually blocked 99.8 percent of damaging UV rays. They 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. Castelli have kept the construction very clean to eliminate seams that can rub, and they used their double-sided silicone elastic to make sure they stay in place. The sleeves fold up extremely small, so they’re great to stick in your pockets for your next big mountain day.
