Baseball Under Shirt Mizuno Pro Red Under Shirt Round Neck Low Neck KUGEKI KUGEKI A cool, mesh-like type. As a loose-fitting under shirt My child used it a few times for school baseball. The sleeves were long, so I had them cut at a specialty store. They are now like 3/4 sleeves. After that, fraying occurred, so I repaired it myself. Please check the photos. Sleeve length: Approximately 35-37cm Since it's raglan, it's difficult to measure the exact length, so this is an approximation. Soccer Innerwear Sports
