The Western Mountaineering TerraLite Sleeping Bag: 25 Degree Down is a very lightweight, warm, and compressible bag that is well-suited for side sleepers due to the flatter hood and the fit, which is wider in some spots, albeit narrower in the shoulders and chest. The narrower fit here was designed to save weight, which keeps this bag very light and easy for packing, while the continuous baffling seals in heat, allowing this bag to be both warm and save on weight.
