Heavyweight 100% Merino Wool Balaclava
When winter throws everything at you, this is what you reach for. The Heavyweight Balaclava delivers serious warmth in a 400 g/m² expedition-weight construction—the same fabric that's been tested on Mount Everest, in the Arctic, and across Antarctic expeditions. The 100% merino wool breathes and manages moisture so you stay warm without the clamminess of synthetics, and the versatile design adapts to changing conditions: wear it as a full balaclava covering nose and mouth, pull the face covering down below your chin, or slip your head through the eye opening to convert it into a neck gaiter. One piece, three ways to wear it.
