Leatt All Mtn 1.0 MTB Helmet 2025

From Leatt, the All Mtn 1.0 MTB Helmet 2025 is a lightweight mountain bike helmet designed to deliver extensive head coverage, including deeper protection at the rear. Built for warm-weather rides as well as steady, low-speed efforts, it combines 14 vents with Maxiflow air channels to keep airflow moving when you need it most.

Leatt’s 360 Turbine Technology is integrated to help reduce peak brain acceleration by up to 30% at impact speeds associated with concussion, and to reduce peak brain rotational acceleration by up to 40%. An adjustable visor with a breakaway function is designed to reduce rotational impact forces, while the in-moulded impact foam supports energy absorption. Finished with a moisture-wicking, breathable inner liner that’s washable, it’s a considered choice for riders who want added coverage without unnecessary weight.
