I received this as a gift, but I'm selling it because I don't use it. It's new! Size M Product Information: This item has high heat retention and quickly absorbs and disperses sweat, keeping your skin dry. The box structure, which connects a smooth surface layer and a soft inner layer with partitions, retains dead air (air that doesn't move as an insulating layer), ensuring heat retention. The smooth surface makes it easy to layer clothing. Suitable for activities that involve repeated action and rest, such as mountain climbing and tour skiing. It's useful in the cold seasons from autumn to spring. Specifications: Material: Geoline® [100% polyester] Average weight: 122g Color: Blue BL Size: M Optimal uses: Mountain climbing / Snow sports Retail price: 5830 yen
