Discover the ultimate addition to your cycling kit - the Castelli Nano Flex 3G Arm Warmers. These arm warmers redefine standards of comfort and protection, making them a must-have for winter cycling enthusiasts everywhere.

Engineered with Castelli's revolutionary Nano Flex 3G fabric, these arm warmers deliver unparalleled rain protection. Through an innovative blend of durable water repellent (DWR) treatment and thermal processing, the fabric causes rainfall to bead and roll off, safeguarding you from wet weather while you pedal.

Internally, Castelli's meticulous R&D has led to a Nano Flex 3G fabric lining that's not only supremely soft, but scientifically designed to regulate body heat in colder conditions. The controlled loft traps just the right amount of warm air next to your skin, maximising temperature control and comfort across various autumn and winter conditions.

Underlining Castelli's commitment to high-calibre cycling performance, the design of these arm warmers is as practical as it is advanced. Courtesy of flat-lock stitching and single-seam construction, these garments maintain a slim profile for flexible wear. A dual-sided silicone gripper ensures secure fitting, while their travel-friendly size lets you slip them easily into your rear pockets as the day warms up.
