A mid-weight insulator of heroic proportions the Arc'teryx Men's Hercules Jacket features high loft shaggy fleece on the inside to capture body heat. Paired with a waterproof breathable shell it offers warmth for the coldest ski days. The exterior is smooth and exceptionally air permeable making the Hercules Jacket an ideal layering piece. Shells slide on easy over it and the breathability makes it an excellent choice for climbing peaks or skinning to the top of untouched powder bowls. To further protect from the elements a laminated hem drawcord keeps spindrift from blowing in and no-lift gusseted underarms keep the bottom of the jacket in place so your midriff doesn't get a shocking blast of cold air.
