Product Description
The AllMtn 4.0 helmet provides DH-certified protection in a lightweight and open design, suitable for aggressive trail and e-MTB riders. Made from shock-resistant EPS + EPO molded foam for better energy absorption, it meets ASTM F1952-15 (downhill MTB) and NTA 8776 (e-bikes up to 45 km/h / 28 mph) standards, making it the ideal choice for aggressive rides and e-MTB adventures. Leatt's 360° Turbine technology reduces rotational forces and absorbs energy from low-speed impacts, while the shock-absorbing foam offers protection against high-speed impacts, working together as a unique 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 case of an accident. With its secure attachment system, integrated sunglasses holder, and sleek design, the AllMtn 4.0 is made for riders looking to push their limits.
