The Leatt MTB AllMtn 3.0 in White is a lightweight open face mountain bike helmet that delivers premium head and brain protection for trail cycling, cross country and backcountry adventures. It is well ventilated, comfortable all day and packed with thoughtful details.

If you want one helmet that handles everything from a quick after-work trail loop to a full day exploring the hills, this is it. It’s the helmet we’d suggest for keen mountain bikers who want a step up in protection and comfort over an entry-level helmet, without moving into heavier enduro territory.

PowerBridge Construction

Leatt’s PowerBridge in-moulded force absorber strengthens the polymer compound shell while keeping weight down. It helps make the helmet safe and stable without adding bulk, so it feels light on your head on long days.

360° Turbine Technology

Leatt’s 360° Turbine Technology uses small, energy-absorbing discs inside the helmet that can move in any direction on impact. They help reduce head impact at concussion level by up to 30% and rotational acceleration to the head and brain by up to 40%, giving you extra confidence every time you head out.

MaxiFlow Ventilation

Nineteen vents and MaxiFlow air channels keep air moving even at slow speeds, which you will appreciate on hot climbs. The Dri-Lex liner is washable, moisture-wicking, anti-odour and breathable.

Practical Everyday Features

Eyewear docks above the visor make it easy to store your sunglasses, with an anti-slip design to keep them in place. The removable visor has a breakaway function, the strap dividers and fit system give a custom feel, and the Fidlock magnetic buckle is easy to use with gloves on.
