UNIQLO UV care. I believe the sleeves were about 8-分 (hachi-bun, a unit of length, likely referring to 8/10ths length) and designed so they wouldn't peek out when worn as an undershirt. I used to wear it under short-sleeved wear when hiking. I bought it because I suddenly needed it, but I haven't used it since, so I'm letting it go. I think it can also be used as an undershirt for walking, running, cycling, golf, etc. Features and Shape: Women's Color: Black Wear Size: M Since there is no UNIQLO in this category, I have selected Under Armour. Please understand. #Closet's Best
