    No more goosebumps.

    Cold arms are uncomfortable and distracting when you're pushing through a cool shoulder-season ride, but it's an easy problem to fix. Slide on the Castelli Thermoflex Arm Warmer before you head out on a crisp day, and the microfleece-lined thermal fabric will hold heat next to your arms while remaining breathable if you break a sweat. Features like a comfortable cross-wrap at the wrist and silicone gripper promise to keep fit issues at bay so you can put each warmer on and go ride free of distraction.

    • Insulate your arms on chilly days with this plush warmer
    • Thermoflex fleece holds heat close but remains breathable
    • Silicone gripper prevents slippage and drooping
    • Cross-wrap cuff creates a comfortable fit at your wrists
    • Item #CST00GM

    It works for me. Very warm! The only cons is that the strap is a little tight and I have thiny arm, but it is bearable.
