Perfect for fighting off the chill on your mountain runs, frozen ascents, and cold weather bike missions, this close-fitting headband offers warmth in a low-bulk and breathable package. It’s constructed using lightweight, wicking Thermic™ S fabric which has alternating stripes of high- and low-lofting fleece, making it highly efficient on weight and providing a fine-tuned balance of warmth and breathability. Slim and built with minimised seams, it fits well under a climbing, skiing, or biking helmet, giving you a little extra insulation without the bulk.
