If you want a sleek looking MMA Rashguard, you should consider the Tapout Elite Camo Rashguard. It features the high-performance fabric that you would expect in a top rashguard. This shortsleeve rashguard has a blend of about 90% polyester and 10% spandex. The Polyester provides breathability and will give you moisture wicking dryness and the spandex will give you stretch and flexibility that will prevent ripping.
The design of this rashguard is pretty cool and is similar to tactical gear with camo pattern and a subdued black color.
