The Womens Helix Vest combines sustainable materials with a technical design. In the body we used our MerinoLOFT insulation, which provides a warm, breathable and natural alternative to synthetic insulations, and the stitch-free patterning ensure maximum warmth. The recycled polyester face fabric features a DWR that sheds light precipitation. Merino jersey stretch side panels help regulate body temperature on active days, and the 100% merino lining ensures a cozy feel inside. Zippered hand and chest pockets keep small essentials like lip balm, snacks and your phone close at hand.
