For cool mornings in the woods, breezy afternoons on the coast or any time when a flannel isn't enough and a jacket's too much, the Helix Long Sleeve Shirt strikes the perfect balance of warmth, style and comfort. The fully reversible design features a solid-print, 100% recycled polyester shell on one side, and super-soft merino plaid flannel on the other for multi-outfit efficiency during long stints away from home. Inside, we used our innovative 70gm MerinoLOFT€š¾€š insulation, a sustainable and high-lofting alternative to synthetic fills made from all-natural merino wool (up to 10% of which is recycled). MerinoLOFT€š¾€š retains warmth when wet and naturally helps regulate body temperature to keep you comfortable, whether you're sipping you're morning coffee on the deck or roadtripping with friends. Snap-buttons on the front placket and cuffs make for easy on-and-off.
