Castelli Nanoflex Arm Warmer
If there is one failing of most warmers its that they absorb water like a sponge. On rainy days they end up waterlogged and providing compromised warmth. The Nanoflex Arm Warmer by Castelli is perfect for riding in conditions that are both cold and wet. Nanoflex is a proprietary Castelli fabric. Despite its water-resistant finish, Nanoflex fabric remains highly breathable, keeping you comfortable in almost any conditions.
