## Long description

The Leatt Helmet MTB Endurance 4.0 is a mountain bike helmet engineered for trail and endurance riding. Designed to balance protection, ventilation, and a performance fit, this helmet suits everyday trail riding, mixed-terrain commuting and recreational off-road cycling. The model 4.0 integrates impact-absorbing construction with airflow channels and an adjustable fit system to provide a stable, comfortable helmet for a variety of MTB conditions.
Advantages
The helmet offers impact management features and a lightweight shell that maintain protection without excessive bulk. Its ventilation design promotes cooling during long rides while the adjustable retention system ensures a secure fit across a range of head sizes. The helmet’s visor provides sun and debris protection without compromising airflow, and interior padding can be adjusted or removed for cleaning and comfort.
Suitable for
Trail and enduro mountain biking
Mixed-terrain commuting and bikepacking

Training rides where ventilation and fit are important
Key specifications
Use type: mountain bike / trail / endurance
Design: lightweight shell with internal impact-absorbing liner
Ventilation: multi-channel airflow system for heat dissipation
Fit system: adjustable retention for precise sizing and stability
Comfort: removable and washable internal pads
Visor: adjustable visor for sun and debris protection
Weight: engineered for a balance of low weight and robust protection
How to use
Position the helmet level on the head so it sits approximately one to two finger-widths above the eyebrows. Adjust the retention system until the helmet feels secure without excessive pressure. Fasten and adjust the chin strap so it forms a V-shape under each ear and can be comfortably tightened with one or two fingers under the chin. Check that the helmet remains stable during head movement and that ventilation channels are unobstructed. Regularly inspect pads and straps for wear and clean removable pads according to manufacturer care guidance.
Usage recommendations
Use the helmet for trail and endurance rides where balanced protection, ventilation and fit are required. Replace the helmet after any significant impact or if structural damage, cracking, or severe wear is observed. Store the helmet away from direct sunlight and high heat to preserve materials and padding.
