Lightweight and stable MTB helmet

The MTB All Mountain 4.0 from Leatt is a must-have for MTB adventures with challenging climbs and fast descents. Its lightweight yet durable construction is not only comfortable, but also provides protection when you’re riding off-road.

Many great features

Featuring a universal sunglasses holder, you can store glasses safely under the visor. This protects them from scratches and hits. The adjustable visor opens up wide enough for you to place them underneath without having to take them off all the time.

Thanks to the Fidlock buckle system, you can quickly open and close the straps. In addition, it boasts the so-called 360° turbine technology, which reduces rotational forces and the impact energy on the head and brain in the event of a fall. It’s completed by openings that let the air circulate through, so your head won’t get too hot.

The features at a glance:

  • Lightweight and durable outer shell
  • Magnetic Fidlock closure system
  • Adjustable visor with breakaway function to reduce rotational forces on impact
  • 360° turbine technology to mitigate impact energies and rotational forces
  • Breathable, odour-resistant and washable lining
  • Injected EPS and EPO foam absorbs the energy
