These CASTELLI UPF 50+ LIGHT KNEE SLEEVES are rated at UPF 50+ officially, but in laboratory tests, they proved to block 99.8 percent of harmful UV rays. Made with a polyester base, these sleeves are more effective than nylon in blocking UV rays and keeping you dry, making them suitable for both cooler and warmer conditions. The design eliminates any rubbing seams and the double-sided silicone elastic ensures they stay in place. These knee sleeves can easily fold up and fit into your pockets, making them perfect for your next mountain adventure.
