Product Description
Castelli Nano Arm Warmer
Due to their anatomic shape and lightness, the Nano warmers feel more natural and bunch less than other windproof warmers. The front side of the warmer blocks the wind with STRATOSHEER LIGHT, the back side is super flexible because of ACTION POWERLYCRA fabric. These two panels are joined by flatlock stitching. Silicone on the inside and outside keeps the warmer in place and prevent the jersey or short from riding up.
