This is a functional short-sleeved T-shirt designed to minimize sweat stains, part of the "Sugo-i" series. It uses ultra-fine "micro-tencel KF" material, offering both cool-to-the-touch sensation and quick-drying properties, making it suitable as an inner layer for spring and summer. There are no noticeable stains, but as this is a used item, I would appreciate it if you could understand.
