At 2.4 pounds, the Suomy MX Jump motocross helmet is the lightest competition-approved helmet sold in the United States. Its tricarboco composite shell is constructed using fiberglass, carbon fiber and Kevlar. The exterior shell has been designed to reduce impact angles, improve aerodynamic flow and accommodate most modern neck braces. Coolmax Active fabric with Interpower treatment wicks sweat away from the body and keeps the rider dry and comfortable. Advanced EPS channels, ram air ducts and fully functional exhaust vents create unmatched airflow.
