Leatt MTB All Mtn 3.0 Cycling Helmet

The Leatt AllMtn 3.0 is a modern trail helmet built around one key priority—protection without compromising comfort.

At the core is Leatt’s 360° Turbine Technology, designed to reduce both rotational forces and low-speed impact energy—two of the main causes of concussion-type injuries. Alongside this, the in-moulded PowerBridge structure helps distribute impact forces more effectively across the helmet.

For eMTB riding, this matters more than most riders realise. Higher speeds, increased bike weight, and longer descents all increase the demands on your protection.

Ventilation is another standout. With around 20 vents and a breathable liner, airflow remains effective even at slower climbing speeds—something particularly relevant for eMTB use where airflow is often reduced.

The result is a helmet that feels light, well-ventilated, and secure—built for long days on the bike, not just short descents.

Key Features

• 360° Turbine Technology to reduce rotational and impact forces
• PowerBridge in-moulded structure for improved energy absorption
• Lightweight polymer shell with extended rear coverage
• 20 ventilation ports for consistent airflow (even at low speeds)
• Fidlock magnetic buckle for easy one-handed use
• Adjustable breakaway visor for added safety
• Moisture-wicking, washable liner

Torque Collective Insight

Helmets are one area where eMTB riders should be thinking differently.

You’re riding:

• faster
• heavier bikes
• longer descents

That combination increases both impact energy and fatigue.

The AllMtn 3.0 sits in a strong middle ground:

• more protective than lightweight XC lids
• far more wearable than full enduro helmets

For most riders, this becomes a daily helmet, not just something for specific rides.

Fit & Sizing

• S: 51–55 cm
• M: 55–59 cm
• L: 59–63 cm
• Adjustable retention system for fine tuning
• True to size for most riders
• If between sizes, go slightly tighter for stability

Who It’s For

• Trail and eMTB riders
• Riders doing longer, mixed-terrain rides
• Anyone wanting increased protection without going full-face

Who It’s Not For

• Lightweight XC-only setups
• Full downhill / bike park only riders (better suited to full-face)
