- Brand: UNDER ARMOUR COLDGEAR - Size: YXL - Color: Navy This is a long-sleeved cold weather garment. I'm selling it because my child outgrew it without wearing it much. It has a lining and is warm, not flimsy. It's COLDGEAR. The name was written on the tag, so it has been blacked out. Please refrain from purchasing if you are sensitive to used items.
