This is the Warehouse long-sleeved border T-shirt "4088". The material is 100% cotton, using a slub yarn with a large wavelength of the thick No. 7 yarn, giving it a wool-like texture. It is based on a cotton baseball shirt from around the 1930s, with a classic specification that does not have ribs around the collar and folds back the body fabric. At the time, swimwear made of wool material with the same specifications also existed, and it is extremely interesting that both were designed with a border pattern to improve visibility. *This product is unwashed, so it is expected to shrink by approximately 1cm in length and 2cm in width after washing.
