This is the UN1050 underwear from Unfudge. Condition: New, only tried on. Color: Black Size: S Waist: Free Total length: Approximately 90cm Inseam: Approximately 71cm The following is a quote from the web page: ＜UN1050＞ This product uses "POLARTEC PowerGrid". It quickly absorbs and wicks away sweat generated during any exercise. In the mountains, intense exercise and rest are repeated. Even if the temperature is low, you sweat. If the underwear that is always in contact with the skin remains wet with sweat, it will rapidly take away body heat during breaks. The UN1050, which has excellent sweat absorption and wicking properties even during breaks, will not cool the body. The lining is brushed in a grid pattern, providing a good feel against the skin, and the high-performance grid structure fabric always maintains a comfortable environment. The sleeve length is designed to follow movements that stretch the arms, such as climbing. The back hem is designed to be slightly longer to fit when maintaining a forward-leaning posture for long periods, such as cycling. ＜Product Details (Specifications/Specs)＞ ・POLARTEC® Power Grid™ ・3.7Oz (125gm) ・91% Polyester / 9% Spandex ・Recycled 90% ・Surface - Face : Jersey / Back : Baby shearling grid ・COSYFORM™ ・Weight / L / 160g ・Price / ¥11,330
