Easy on the weight. Heavy on the warmth.
They say "good things come in small packages." And after developing this jacket, we can confirm that's true. Outside, you get lightweight, flexible, water-resistant fabric. Inside, 800 fill power HyperDRY down (the kind that dries in a flash and stays warm even when wet). All three exterior pockets have zippered closures to keep your gear secure. The full-zip front has a hidden storm flap to prevent the dreaded "cold front." And here's the kicker: the whole thing packs into its own pocket. For powerful warmth ... in the palm of your hand.
