Shut out the wind at your collar with the Pro Thermal 3 Neck Warmer
What Our Gearhead® Experts Are Saying:
"I keep this stuffed in a pocket for early starts and pull it up over my neck the second the wind picks up on a descent. On warmer days, I've even folded it down and worn it as a cap instead."
A gap at the collar is all it takes to let the cold in, and Castelli built the Pro Thermal 3 Neck Warmer to close it off completely. We love how one simple tube of Thermoflex fabric handles three jobs: neck warmer, bandana, or cap, so a single piece adapts to whatever the ride throws at us instead of packing three separate options.
