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. Using a polyester base they found this it is not only more effective than nylon at blocking UV rays but is also much better at keeping you dry, which means these skins are better in both cooler and warmer conditions. Castelli have kept the construction very clean to eliminate seams that can rub, and used 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.
Most warmers available are made from a nylon/elastane material and they tend to hold onto moisture, meaning they may be warm to start but they'll soon have you feeling chilly and damp when you get going. However, the Pro Seamless Knee Warmers use a polyester yarn, far better for dealing with sweat build-up while still maintaining excellent warmth. Just what you need for cool weather, hard training and intense racing. Thanks to the low weight, high stretch and seamless construction you'll barely notice them either. If the day warms up they'll fold up small and easy fit in a cycling jersey pocket.
