This is an Under Armour high-neck undershirt. The back is mesh. It's a size M and the color is navy. I tried it on once after purchasing it, but it was too small, so I'm selling it. I've stored it carefully, but please understand that I'm a private seller. I'm open to discussions about discounts and combined purchases in the comments. I will cover the shipping costs. - Brand: UNDER ARMOUR - Size: M - Color: Navy - Design: High Neck Thank you for looking. Sleeve Length...Long Sleeve Gender...Men
