Leatt Helmet MTB AllMtn 4.0 Stealth M

The AllMtn 4.0 helmet delivers DH-certified protection in a lightweight, open-face design—giving aggressive trail and e-MTB riders downhill-level impact protection. Built with in-molded EPS + EPO impact foam for enhanced energy absorption, it is certified to ASTM F1952-15 (downhill MTB) and NTA 8776 (e-bikes going up to 45km/h / 28 mph) standards—making it an ideal choice for aggressive rides and e-MTB adventures. Leatt’s 360° Turbine Technology helps reduce rotational forces and absorb low-speed impact energy, while the impact foam provides high-speed impact protection—working together as a 3-in-1 safety system. The modern profile meets the highest safety standards, yet it remains lightweight and breathable, with a moisture-wicking liner to manage sweat. A Fidlock magnetic buckle makes for easy one-handed closure, and the adjustable breakaway visor adds another layer of protection in a crash. With a secure fit system, integrated eyewear dock, and sleek design, the AllMtn 4.0 is built for riders pushing the limits.
