What Our Gearhead(R) Experts Are Saying:"I bring the Summit Dotknit Balaclava on every winter mission-whether it's a pre-dawn skin up the ridge or a summit push in biting wind. It fits perfectly under my helmet and actively pulls sweat away so I don't overheat or freeze up when I stop."In the mountains, versatility is survival. The Summit Dotknit Balaclava from The North Face is a crucial layering piece when we're battling windchill on exposed ridgelines, carving early-morning powder laps, or pushing uphill in frigid temps. Built for climbing, snowsports, and running alike, this balaclava balances breathability with insulation-just what we need when conditions are dynamic and our energy output fluctuates. Its DOTKNIT(TM) fabric blends recycled polyester and RWS-certified wool, offering next-to-skin softness, odor resistance, and adaptive moisture management thanks to FlashDry-Pro(TM) technology. A hinged design makes it easy to pull down during transitions, and the under-helmet fit keeps it low-profile and secure during technical missions. Plus, UPF 40+ adds sun protection on those high-altitude bluebird days.
