Designed for wear in extremely cold environments, with an emphasis on heat retention. It warms the body from the core with radiant heat, and the three-layer fluffy air layer prevents warmth from escaping. Despite its thickness, it is lightweight and highly stretchable, allowing for comfortable layering. The product condition is considered to be "no noticeable scratches or stains." Please note that it will be shipped in a compact size. I also have various items for sale from Uniqlo, Muji, The North Face, Patagonia, Montbell, and Workman.
