A super-lightweight yet seriously effective ThermoBall-insulated boot from The North Face is cut from water-resistant recycled P.E.T. ripstop for durability and protection from the elements. The ThermoBall insulation gives you the same warmth as 600-fill down with the added bonus of wet-weather insulation, and the recycled ripstop shaft keeps mud and snow from setting up camp. The barrel-lock drawcord and gaiter locks out cold breezes-plus, you'll be stepping sure thanks to the TNF Winter Grip rubber and IcePick temperature-sensitive lugs for superior, adaptive traction. Brand: THE NORTH FACE. Style Name:The North Face Thermoball Ii Water Resistant Boot (Men). Style Number: 758715. Available in stores.
