The T-shirt is a low-tier chest-covering armor item that contributes protection to the torso portion of a RUST player.
There are two variations of the t-shirt, one being the Longsleeve and the other being an ordinary t-shirt. While sharing the same projectile and bite protections, the sleeveless t-shirt is inferior to its sleeved counterpart in both the cold and radiation protection statistics it has.
Aesthetically, the only apparent difference is the sleeves and the base color. Both shirt types behave in the same way, occupying the primary chest covering slot on the character model.
T-shirts are commonly found in low-to-mid-tier crate types, as well as frequent drops from most Scientist NPC types. Players may learn them directly via the research table or by investing scrap into the Tier 1 Work Bench tech tree. They are also available for purchase directly from Output Outfitters, the clothing vending machine at the Outpost monument for 5 Scrap.
