The Altitude Adjustable Vest

This is the air-insulated weatherproof vest that keeps you warm whether climbing the Great Smoky Mountains or enjoying a winter night stroll. Available only at Hammacher Schlemmer, its integrated in-pocket pump and release valve enables you to increase or decrease the amount of its air-insulation, operating like a dual pane window to provide you with up to 30° F of additional warmth. Built to withstand the rigors of outdoor adventures and extreme weather conditions, the lightweight vest’s durable, rip-resistant nylon shell repels moisture, keeping one dry. Its full-length zipper and draw cord waist helps maintain a body’s core temperature and seal in heat. With two exterior zippered pockets and two spacious interior pockets for a smartphone and tablet. Imported. Black. Men’s sizes S (35-37), M (38-40), L (42-44), XL 46-48). (1 lbs.)
