Description

The AllMtn 2.0 helmet combines trail-ready features with proven protection for riders who are always looking forward to their next adventure. With Leatt’s 360° Turbine Technology, it helps reduce rotational forces and absorb low-speed impact energy, while in-molded impact foam provides high-speed impact protection—working together as a 3-in-1 safety system. The lightweight polymer shell features 20 vents for consistent airflow, and a breathable, moisture-wicking liner keeps you dry through the climbs and descents. A Fidlock magnetic buckle makes it easy to secure the helmet with one hand, and the adjustable breakaway visor adds an extra layer of safety in a crash. With trusted Leatt protection and comfort, the AllMtn 2.0 is ready for your next big day on the trails.

Super nice quality and comfy

This is my first Leatt half shell and the quality is just amazing. Very light and solid and the Fidlock system is a really nice addition.

My head circumference is exactly 55cm and the size small fits perfectly with room to spare. Will definitely recommend getting one to anyone looking for a new helmet.
