EVS Sports – Shoulder Braces, including the SB03 Shoulder Brace in Black in Medium, XL and 2XL. A dislocated or separated shoulder is among the most common injuries in motocross, ATV and trail riding, and once the joint has been stretched it stays loose. The SB03 works by limiting how far the arm can rotate and abduct, holding the humeral head in the socket during a crash or an arm-wrenching save while still letting you steer, pull a clutch lever and hang off in corners. The rigid outer cups spread impact away from the joint, the internal strapping lets you dial the range-of-motion stop, and the low-profile shape sits under a jersey or chest protector without bunching. Riders coming back from surgery use a shoulder stabilizer brace to build confidence, while healthy riders run one as cheap insurance for a joint that never heals back to stock. The brace moves easily between bikes, quads, sleds and race weekends. Sizing is based on chest measurement, not jersey size, and a brace that is too large will not hold the joint. Send us your measurements and we will confirm the right EVS SB03 size before you order.
