Leatt MTB All-MTN 4.0 Helmet

When trail riding moves up to the next level and you are challenging mountains. The mountain will call you at one point or another, so be prepared! The Leatt MTB All-MTN 4.0 Helmet features a universal sunglasses dock lets you safely dock your sunglasses under the visor when not in use, protected from scratches and unwanted impacts. The adjustable visor opens up enough to place your goggles underneath, so you don’t have to constantly remove them. You will also love the convenience of the Fidlock buckle system.

Leatt helmets feature 360 degree Turbine Technology reduces both rotation acceleration and concussion level impact energy to your head and brain! Do not be afraid to push you limits. Gear up and be prepared for whatever is waiting along the trail.

Features:

  • Lightweight Polymer shell
  • Sunglasses dock port for easy, secure storage
  • Fidlock magnetic closure system
  • 360 degree Turbine Technology
  • Reduced peak brain acceleration by up to 30% at impact speeds associated with concussion
  • Reduces peak brain rotational acceleration by up to 40%
  • Adjustable visor with breakaway function for rotational impact force reduction
  • Maximized ventilation with 18 vents. Optimized for riding and effective even at low speeds
  • Moisture wicking, breathable, anti-odor and washable inner liner
  • In-molded EPS + EP0 impact foam for superior energy absorption

Note: Bicycle use only, not DOT-approved and not intended for use with motorcycles.
