The men’s Helix Long Sleeve Shirt strikes the reversible balance between a light fall jacket and a woodsy flannel shirt, perfect for cool mornings in the forest or breezy afternoons by the sea. It features a 100% recycled polyester shell on one side, and Icebreaker’s soft merino plaid flannel on the interior. It’s also padded with 70gm of MerinoLOFT™ insulation, which retains abundant warmth for its weight and acts as a sustainable and high-lofting alternative to synthetic fills. MerinoLOFT™ even retains body heat when wet and naturally helps regulate temperature. The classic snap-buttons on the front placket and cuffs make changing in-and-out of this reversible jacket easy.
