New for 2016 is the Phantom 6000 by Scarper! Alaska, Aconcagua, and the Canadian Rockies in winter...lighten up a couple hundred grams from the 8000, but take all the high-altitude burl with you in the Phantom 6000. Same Schoeller®, Kevlar®, and Cordura® outer material with Outdry® for weatherproof durability. Stay dry behind a Flexseal® waterproof closure. Hoard your heat with the felt and 4mm-EVA inner boot. Don\'t even consider a sloppy fit, either: we use a quick-lacing system with Dyneema cord for strength and a progressive fit. Climb steep water ice, slog snowy ridges, and walk in comfort. The Phantom 6000 delivers the comfort and climbing performance of a leather boot, but the warmth and multi-day versatility of a double boot. Go big!
