This balaclava is made with breathable, high-performance Thermolite® fabric to boost comfort as you climb, hike, ski and more. The nylon fabric fibres trap warm air to generate heat while also regulating temperature. This prevents overheating, especially when wearing with a helmet. A water-repellent finish shields against rain and snow. On the inside, a brushed lining offers next-to-skin cosiness and extra insulation. Mesh side perforations and a nose and mouth opening enhance breathability and help stop goggle fog. The all-way stretch makes getting the balaclava on and off easy. And the design provides excellent pill resistance and a UPF50+ rating. For extra warmth and protection as you explore the mountains, the unisex Balaclava Light Cap has you covered.
