MMA brand from America. Loved by many top domestic and international fighters, including UFC and RIZIN fighters. These items are now rare and not widely sold in Japan. Training wear (jersey material). The back is partially mesh, designed for breathability and heat release. The yellow lines are a highlight and look cool. Size: XL (American size. Feels about 1.3 times larger than Japanese sizes) This is a new item that has been stored for a long time.
