The Castelli Pro Seamless Arm Warmers give you the ideal balance of warmth and breathability while remaining light and easily packable. With no seams, they're also incredibly comfortable. What more could you want?
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, the excellent moisture-management prevents you 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.
Castelli proudly produce high performance cycling apparel. Since 1876, they've been the tailor for the champions. It was their innovative mindset which brought the earliest heroes & legends like Binda, Coppi and Bartali. Castelli cycle clothing became legendary too inventing the skinsuit, the silk jersey, pockets on jerseys, and the first LYCRA® short used in professional racing.
