Castelli can officially only rate these warmers at UPF 50+, but in their laboratory tests they 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.
