Unused item, only opened for inspection. Stored after being purchased new. No hydrolysis of seam tape. Size: 87cm (shoulder width) x 209cm (total length) [Reference] Based on ultra-lightweight 30-denier nylon, this model uses a three-layer Gore-Tex material and is designed with a relaxed, wide fit, making it ideal for winter mountaineering. Especially when using a large loft winter sleeping bag, a wide model or a larger size of sleeping bag cover is comfortable without compromising the loft. The three-dimensional cut hood is designed to reduce pressure, and the 60cm side zipper makes it easy to get in and out. In addition to the excellent waterproofness of Gore-Tex, its high breathability minimizes the accumulation of moisture in the sleeping bag due to insensible perspiration during sleep.
