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.
The Graffiti Cycling Armwarmers are a cycling accessory that prove their worth year-round. Thanks to the use of insulating Thermoflex fabric, they're ideally suited to wear on an early summer morning start or to take off the bite of cooler spring and autumn temperatures. The anatomic cut ensures they fit comfortably when you're in a riding position. And with silicone grippers, they hold tight under your jersey sleeves.
With their Pro Seamless Arm Warmers, Castelli have started from scratch to create a better product. Other brands tend to use a simple nylon/lycra blend that holds moisture. Not good. Instead, Castelli have turned to Polyester to improve moisture management - it's harder to get right in terms of stretch, return and manufacturing consistency, but the benefits paid off in the end. The Pro Seamless will surprise you with how light they are and yet they're surprisingly warm too. Even as the weather turns mild, excellent moisture management prevents you from overheating. A high degree of stretch makes them brilliantly comfortable and when you take them off to stash in a pocket they take up a fraction of the space of normal warmers.
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 Leg 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 fast 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.
