This is a long-sleeved T-shirt from AKTR's women's series. The size is 2XL, which is equivalent to XL for men. I've worn it about 5 times as casual wear after purchasing it, and it's still in good condition. The material is 100% polyester, but it's AKTR's original Dry Tech fabric, which feels like cotton. It can be used for both casual wear and exercise, so please consider it. AKTR, Actor, Basketball, Long Sleeve T-shirt, Sweatshirt, Trainer Thank you for looking.
