Nanoflex Arm Warmer

Sorry, this product is no longer available.

Castelli’s pro-look armwarmer, with performance to match. These amazing armwarmers do more than just protect you from the cold—they’re also very good at keeping out rain! They breathe, stretch, and warm like most armwarmers, but repel water like no other. Perfect for any condition, these can be a real lifesaver (and with that classic Castelli style, they add a little snap to your outfit).
