The Leatt Body Tee 3DF AirFit Lite Evo is a protector that is usually long-sleeved. The exact sleeve length is not explicitly mentioned in the information provided, but there is also a short sleeve version labelled as a "short sleeve 3DF AirFit Body Tee protector". If you're unsure, I recommend checking the product description or pictures on the manufacturer's website to make sure it's the long-sleeved version.
