Leatt MTB mask designed for hot outings: WideVision bulletproof anti-fog lens, self-draining ventilated frame, double-layer foam and 40mm mesh strap.

LEATT Velocity 4.0 MTB Goggles — Maximum ventilation and certified eye protection for trail running

The LEATT Velocity 4.0 MTB mask in flame orange clear 83 vlt is the benchmark for riders looking to combine optimal airflow, all-day comfort and uncompromising eye protection on hot and dusty trails.

Screen and optics

The RideViz MTB WideVision lens offers a generous 170° field of vision, ensuring complete awareness of your surroundings in all conditions. Its clear tint boasts an 83% VLT (Visible Light Transmission) rating, ideal for low-light conditions or riding in wooded areas. The permanent anti-fog coating keeps vision clear even during intense activity, while the scratch-resistant coating preserves optical quality over time. The ANSI Z87.1-2015 standard and the MIL-DTL-43511D ballistic impact standard certify the impact resistance of this bulletproof lens, and the goggle complies with PPE (EU) Regulation 2016/425. Replacement Velocity lenses are available separately to adjust the VLT to suit different conditions.

Headband and comfort

The dual-layer face foam features a moisture-wicking backing that maintains a comfortable fit against the face, even during long summer rides. OTG (Over The Glasses) compatibility allows riders who wear prescription glasses to use the goggles without discomfort or added pressure. The 40mm MaxiVent anti-slip mesh strap sits perfectly on the helmet while keeping the goggles securely in place.

Aeration

The Velocity 4.0's frame is designed around an active ventilation principle: large mesh vents across the entire frame promote generous airflow while blocking mud and dust particles. The lower part of the frame features an open, self-draining design, preventing dirt buildup on the lens and thus minimizing interruptions to clean the lens.

Headset compatibility

The 40mm MaxiVent headband is specially sized to avoid obstructing the vents of modern mountain bike helmets, thus preserving ventilation for the entire head and gear system. The OTG (Over-the-Top) design also ensures optimal compatibility with any type of helmet.
