    • Castelli Pro Seamless Arm Warmers SS20

  • Castelli Pro Seamless Arm Warmers

    The Castelli Pro Seamless Arm Warmers are both warm and breathable, making them ideally suited to cool days on the bike but where your ride intensity could be high. They're also remarkably light and with no seams incredibly comfortable to wear.

    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.
