LEATT AllMtn 3.0 MTB Helmet — Tri-technology all-mountain protection for challenging trails

The LEATT AllMtn 3.0 MTB Helmet in stealth black/grey is designed for riders who tackle long sessions on demanding trails without ever compromising on protection. Thanks to its innovative 3-in-1 safety system, it covers the full spectrum of risks encountered in all-mountain and enduro riding, from minor impacts to high-speed collisions and rotational forces.

Construction and materials

The lightweight polymer composite shell ensures an optimal strength-to-weight ratio. It incorporates a molded PowerBridge structure that significantly improves the absorption of high-energy impacts. Impact foam is molded directly to the shell to ensure excellent energy dissipation during a collision, without any play or unwanted material displacement. The result is a robust helmet, designed to last on terrains where every detail counts.

360° Turbine Technology

At the heart of the helmet, Leatt 's exclusive Turbine 360° technology deploys a three-level protection system:

  • Reduction of rotational forces : the geometrically optimized "turbine" discs allow slight movement of the helmet on the head during impact, thus reducing the maximum acceleration transmitted to the skull and brain.
  • Low-speed impact absorption : the turbines absorb the energy of low-amplitude shocks, which are common on technical trails.
  • High-speed impact protection : the PowerBridge combination and molded impact foam take over for the most violent impacts.

This unique 3-in-1 system positions the AllMtn 3.0 among the best-protecting helmets in its category, without the need for additional components.

Ventilation

Twenty generously sized vents run across the shell, ensuring efficient airflow even at low speeds or during technical climbs. Air circulates actively throughout the entire shell, quickly dissipating heat and maintaining a comfortable wearing temperature on long summer rides.

Comfort and fit

The helmet's interior features a breathable, odor-resistant, and washable lining that wicks away moisture quickly, ensuring lasting comfort even in hot weather. The occipital retention system with a micrometric buckle allows for precise and personalized adjustment, guaranteeing optimal stability for all head shapes. The Flat Lock strap divider keeps the chin straps in the ideal position under the ears, preventing irritation. The helmet can be fastened with one hand thanks to the Fidlock magnetic buckle, which is especially convenient when wearing gloves. Integrated slots allow for easy and secure storage of sunglasses. The visor is both adjustable and detachable; in the event of a fall, its design helps reduce rotational impact forces transmitted to the helmet.
