On a long weekend run that crosses exposed ridges and drops into sheltered trails, the Ciele GOCap-FLTWND-UltraIconic is the cold-weather running cap that adapts. Fold-away ear flaps cover the ears when wind and cold hit and fold up once the temperature rises. The outer fabric resists wind and rain, and recycled polyester and carbon in the main knit help regulate temperature on the climbs. What Our Gearhead(R) Experts Are Saying:"Folding the ear flaps up at the top of a climb kept me from overheating once the wind dropped, and I flipped them back down on the next exposed stretch. After the run, the soft brim folded flat enough to stash in a jacket pocket."
