Castelli Thermoflex 2 Arm Warmer Black, M

The Castelli Thermoflex 2 Arm Warmer features a Thermflex fleece fabric that keeps us warm during cold-weather rides as the fleece interior traps warmth against the skin. It features a high stretch that allows for a snug fit with optimized aerodynamics, while the dual-sided silicone gripper elastic at the top prevents it from sliding down the arm.
