Pro Thermal 3 Neck Warmer

What Our Gearhead® Experts Are Saying:

"I run this on any ride where temperatures might swing from cold start to warm finish. It works as a neck warmer on the way out and folds down into a cap once I've shed a layer or two."

Castelli built this neck warmer from Thermoflex fabric, warm, soft, and stretchy enough to seal the collar gap between jacket and helmet without restricting neck movement. Flat lock stitching keeps the seams from irritating skin across long, repeated wear.

Versatility is the core function here, one tube of fabric that converts between neck warmer, bandana, and cap depending on conditions and preference. This is the piece we reach for on rides with an uncertain temperature curve, small enough to carry as insurance and functional enough to solve more than one problem at a time.
