This is a short-sleeved crew neck undershirt from SSK (エスエスケー). The color is navy, and the size is XO. The material is soft to the touch, but it's not flimsy; it's a fairly sturdy garment. There are no noticeable stains. It's a relatively well-maintained garment, but it is a used item, so please understand the condition before considering a purchase. I have many other SSK and baseball wear items for sale. #KamiSSK #KamiBaseballWear #KamiUndershirt #KamiCompressionWear #KamiShortSleeveWear #KamiTShirt I also have a large number of sports wear items from brands like Nike, Adidas, Under Armour, Athleta, Puma, Kelme, Umbro, Asics, Descente, New Era, Oakley, Canterbury, CW-X, and The North Face, as well as baseball wear from brands like Mizuno Pro, Adidas Professional, Under Armour Baseball, SSK, Asics, ZETT, Rawlings, Nike Baseball, Asics Baseball, Majestic, Mitsuwa Tiger, and Activem.
