Leatt builds off-road and adventure helmets around its 360 Turbine technology, a rotation-management system engineered to reduce energy transfer to the head and brain in a crash. This range pairs lightweight composite and polymer shells with Leatt 5.5 ADV touring pants, giving dirt and trail riders matched head-to-leg protection from one brand.

How to choose your Leatt gear
Leatt protection is built on its neck-brace heritage, so every helmet is engineered to work with a brace and to manage rotational force. The 360 Turbine system uses small turbine inserts inside the liner to absorb energy at two points: at low speed to reduce concussion risk, and at high speed to reduce peak brain acceleration. Pick your shell by riding discipline first, then fitment.
| Range | Use | Shell | Certification |
|---|---|---|---|
| 2.5 Helmet | MX / trail | Lightweight polymer | ECE 22.06 |
| 3.5 Junior | Youth off-road | Composite, sized 49 to 54 cm | ECE 22.06 |
| 5.5 ADV Pant | Adventure touring | 600D and 1000D textile | EN 17092 AA |
Fitment and sizing
Measure your head circumference in millimetres around the widest point above the brow. Leatt helmets run from a youth 49 cm shell up to adult 64 cm, with multiple shell sizes so the helmet sits low and even. The 5.5 ADV pants accept CE Level 1 and Level 2 hip and knee armour, and adjustable knee pockets let you set the armour 30 to 40 mm for your leg length.
Armour and abrasion
Adventure riding demands abrasion resistance, not just impact padding. The 5.5 ADV textile carries an EN 17092 AA rating, using a 1000D outer in the high-wear seat and knee zones with a 600D body for airflow. Run CE Level 2 armour in the knees for the highest tested impact transmission limit of 20 kN, and Level 1 at the hips where bulk matters more than coverage.
Frequently asked questions
What is Leatt 360 Turbine technology?
It is a rotation-management system using turbine inserts inside the helmet liner. The turbines absorb energy at two points: reducing rotational acceleration to the brain at high speed and lowering concussion risk at low speed. Every Leatt off-road helmet here is built around it.
Are Leatt helmets certified for road use in Australia?
The Leatt off-road and adventure helmets in this range carry ECE 22.06 certification, the current European standard accepted in most Australian states. Always confirm your state road rules before riding on public roads, since helmet acceptance varies by jurisdiction.
Do Leatt 5.5 ADV pants come with armour?
The 5.5 ADV pants are built to accept CE Level 1 and Level 2 knee and hip armour in dedicated pockets. Knee armour position is adjustable across 30 to 40 mm so you can set protection to match your leg length and riding stance.
