Leatt AllMtn 4.0 MTB Helmet

Leatt’s AllMtn 4.0 MTB Helmet offers a streamlined approach to protection on the trail. It’s lightweight, durable, and strikingly technical without ever feeling too complicated or overbearing. A lightweight polymer shell works in tandem with Leatt’s 360 Turbine Technology and an in-molded EPS foam to create a puncture-resistant and impact-resistant profile that remains ultra-protective against heavy hits and rotational forces. The implementation of Turbine Technology allows the AllMtn 4.0 Helmet to reduce brain acceleration by up to 40%. As a result, the brain is spared from the high impact speeds associated with a concussion. When combined with an adjustable breakaway visor, the AllMtn 4.0 Helmet becomes even more prepared to lessen the likelihood of a rotational injury. A moisture-wicking, quick-drying, anti-odor liner pairs with 18 ventilation channels to keep this MTB-specific helmet fresh, dry, and comfortable through every mission. It’s certified and tested for superior impact protection, and it remains exceptionally comfortable every step of the way. It doesn’t have the full-face frame of its Enduro counterparts, either, so the AllMtn 4.0 remains a bit more versatile and a touch less aggressive than other performers in Leatt’s helmet lineup.
