I purchased this at a sports shop while traveling. I bought it intending to give it to someone, but the opportunity never arose, and time has passed, so I'm putting it up for sale. Size: S (Seems to correspond to a Japanese size M) I think it's a good deal, as it's sold for around 27,000 yen on Rakuten and other sites! There is some fading on the 2XU print logo on the back. Please be aware of this before purchasing. ↓ Quoted from the following site: Product Features ・Outstanding Aerodynamics The 3D structure of SBR CHANNEL and the seamless sleeve finish provide excellent aerodynamics through the shoulders and side panels, ergonomically designed to fit the body like a second skin. ・Stay Cool The SBR VENT upper body, using a hydrophilic nylon Lycra® fiber matrix, enhances moisture and airflow management. ・Powerful & Lightweight Support The powerful and lightweight PWX material provides 360-degree stretch to reduce muscle movement and prevent fatigue. Also, the silicone-printed leg grippers provide an aerodynamic, streamlined fit. ・TMF® Aero Tri Chamois Designed for mid-distance races, the 90-density, 6mm square air channel structure optimizes drying speed. Also, Skyve technology shaves the edges of the pad, providing maximum support where needed and minimizing unnecessary bulk. ・Essential Storage The envelope-style pocket on the back is suitable for safely storing race-day essentials.
