Purchased in January 2025. I am selling it because I have no plans to use it. The retail price is 58,800 yen including tax. Thank you. The following is the manufacturer's description: Features NANGA, a down sleeping bag manufacturer committed to domestic production. Using safe and high-quality down (feathers), The products created through unique sewing techniques are "warm and light." A square model has been added to the popular NANGA and sotosotodays collaboration "sleeping bag"! The standard model is for people up to 178cm tall, but the sotosotodays original is for people up to 180cm tall. It is a size that can be used even by tall people. The outer fabric uses Auroratex(R) (porous polyurethane waterproof coating material), so you can use it directly without a sleeping bag cover. The 600DX is a sleeping bag that can be used for 4 seasons depending on how you use it. About Auroratex(R) The outer fabric material is a porous polyurethane waterproof coating material. This material solves the problem of reduced vapor permeability when waterproofing is increased, and it contains ultrafine particles in the polyurethane resin to form numerous micropores of 0.1um (1 micron = 1/1000mm) or less in the coating film. With a 2-layer construction, it achieves a high level of waterproof and breathable performance with a water pressure resistance of 20000m and breathability of 6000g/m2/24hrs, preventing rain particles of 10um or more while allowing vapor of 0.0004um or less to pass through.
