Oros, a performance outerwear brand based in Portland has created the warmest jacket on earth. Utilizing an advanced insulating material developed by NASA, the Orion Parka features Solarcore, the brand name for this space-age Aerogel insulation. Originally used to insulate the Space Shuttle in deep space where temps drop to -450º, Oros is one of the first to use it in apparel. The brand did some serious engineering to achieve this but their jacket is warmer than down with none of the bulk. Solarcore is also breathable for carefree comfort in variable conditions. Other options are available including mid-layers, bottoms and accessories.
