Under Armour Long-sleeve Shirt, 1/2 zip, cold gear, XS. Thumbholes in the sleeves. It has a slight stripy pattern; I’d also say it’s almost between a dark charcoal grey and black (you can see from the pictures it kinda photographs differently). It’s NWOT, it was just too small for me and I never wore it except to try it on. A shame, as I really love Under Armour and especially the thumbholes.
