Castelli Pro Seamless 2 Arm Warmers

Castelli Pro Seamless 2 Arm Warmers Designed in collaboration with World Tour riders, the Castelli Pro Seamless 2 Arm Warmers offer the best possible warmth-to-weight ratio and are incredibly comfortable. They utilise a unique blend of materials to keep them light and stretchy for freedom of movement, and will pack down small to stash in a jersey pocket when no longer required.
