Designed to perfectly brace your arms during uncertain weather conditions, Castelli brings you the Pro Seamless 2 Arm Warmers. These warmers are more than just an accessory, they’re a biking must-have, configured meticulously in partnership with World Tour riders.

Say goodbye to uncomfortably damp and heavy clothing whenever you ride. While most warmers use a combination of nylon and Lycra® that tends to retain moisture, this Castelli Pro Seamless Warmer is crafted with a distinct blend including polyester, which resists moisture accumulation, keeping you comfortable on long rides.

Castelli dedicated an extra year to perfect the blend of material, ensuring these warmers not only provide unrivalled breathability but also present an exceptional warmth-to-weight ratio – making them a favourite among many professional riders. Their incredibly stretchable fabric ensures you barely feel them on, while their compactness proves advantageous when you have limited pocket space.
