The AllMtn 4.0 helmet offers DH-certified protection in a lightweight, open design, ensuring aggressive trail and e-MTB riders get downhill-level impact protection. Built with molded EPS + EPO anti-shock foam for better energy absorption, it is certified to ASTM F1952-15 (Downhill MTB) and NTA 8776 (e-bike up to 45 km/h / 28 mph) standards, making it the ideal choice for aggressive riding and e-MTB adventures. Leatt's 360° Turbine technology helps reduce rotational forces and absorb low-speed impact energy, while the anti-shock foam provides high-speed impact protection, working together as a 3-in-1 safety system. The modern profile meets the highest safety standards while remaining lightweight and breathable, with a moisture-wicking liner to manage sweat. The Fidlock magnetic buckle allows for easy one-handed closure, while the adjustable visor adds an extra layer of protection in a crash. With a secure fit system, integrated eyewear storage, and a sleek design, the AllMtn 4.0 is built for riders who want to push their limits.
