I have kept this item stored, unused and unopened, since purchase. It's an extremely warm Heattech Cotton Crew Neck T-shirt in black, size 150, with a fluffy, warm inner material made of 100% cotton. I'm selling it because I don't wear long-sleeved underwear. ^ ^ Please understand that this item has been stored at home, so please only purchase if you are okay with that. It will be shipped in an envelope or cardboard box as is. It may be compressed to keep it within 3cm.
