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

Castelli Arm Warmers

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Medium

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.

Hi, I'm 5'8, 145 lbs and was going to get a size small. The medium works for you?
