Leatt

MTB 4.0 Enduro Helmet

What Our Gearhead® Experts Are Saying:
"This helmet gives me confidence on everything from mellow trail rides to full enduro stages. The removable chin bar is a game changer—breathable when climbing, protective when descending."

We love a helmet that keeps up with our ride style, and the Leatt MTB 4.0 Enduro Helmet does exactly that. It’s built for the modern trail rider who climbs hard, descends fast, and wants DH-level protection with everyday versatility. Whether we’re lining up for an enduro stage or heading out on a big loop, the 4.0 has us covered.

This convertible helmet features a removable chin bar that attaches quickly without tools, letting us adapt on the fly. It meets ASTM DH certification with the chin bar in place, giving us full-face protection for big lines and bike park laps. 360° Turbine Technology reduces rotational impact forces, while 22 vents and a moisture-wicking liner keep airflow dialed for long climbs and warm weather. Add in adjustable visor clearance for goggles, and it’s ready for everything from technical backcountry rides to shuttle days.
