The lightest jacket in our Mythic series slashes weight and maximises warmth with body mapped insulation and ultralight construction. Down filled baffles are centred around the core while resilient synthetic insulation on the sides, cuffs, shoulders, and base of the hood breathes and manages moisture efficiently. Using only the best insulation, 900FP down and PrimaLoft® Gold, this jacket is incredibly warm for its weight and bulk.
