Purchased in 2018 for running. Worn about once or twice a month for running for about a year. After that, I stopped running, so it has been stored at home. There is a black spot stain on the inside of the right arm (see photo 8). Other than that, the condition is good, and I think it can still be worn. Reversible design. Size: L, Men's Worn by someone 180cm tall and weighing 75kg.
