The Orange Longsleeve T-Shirt is a piece of clothing in Experimental Rust. It provides good cold protection, as well as decent bullet, melee and radiation protection. It is presumed to be slightly worse than the Jacket, but better than the Green T-Shirt, even though the T-shirt and Longsleeeve have identical stats.
This is like a normal tshirt, but it has sleeves that extend to your wrists.This is a skin for the Longsleeve T-Shirt item. You will be able to apply this skin when you craft the item in game.
