Castelli Pro Seamless 2 Arm Warmer

The Avant Garde design of Castelli’s Pro Seamless 2 Arm Warmer keeps arms warm in cool weather, but at the same time use it to keep sun off your arms in warm summer weather. The warm fabric is combined with highly breathable fabric to keep air circulating so you don’t over-heat. The soft, seamless construction is very comfortable and it’s 52-gram weight creates a pair of arm warmers that feel nearly weightless. When you want to take the Pro Seamless 2 Arm Warmers off, fold them in a small packet to easily store in your rear jersey pocket.
