The Storm King is Big Agnes' warmer version of the Lost Ranger. If you are a cold sleeper or spend more time camping when your dog's water bowl is frozen and the crowds are long gone, this is the bag for you. The Storm King uses a 20 inch rectangular pad in either long or regular depending on the bag you choose. The DownTek down insulation keeps you warm, even if your bag gets wet, by repelling the water on a microscopic level. The Storm King combines a roomier contour shape with a narrower pad sleeve to provide an overall more comfortable and cozier sleeping experience than ever before. The ergonomic hood gives you more range of motion so that you can move unrestricted while staying hooded.
