With 360° Turbine Technology to help reduce rotational forces and absorb low-speed impact energy, plus in-molded impact foam for high-speed impact protection, it offers a 3-in-1 safety system you can count on. The polymer shell includes extended rear coverage for added protection, while 14 vents keep airflow moving on climbs and descents. An adjustable fit system ensures a secure, personalized fit, and the Fidlock magnetic buckle makes for quick, one-handed closure. Whether you're just starting out or looking for dependable performance without the premium price, the AllMtn 1.0 has you covered.

Top performance at a very friendly asking price

The Leatt MTB AllMtn 1.0 helmet is one of the brand's cheapest options, though it still packs a useful array of tech for the money. While it fits rather narrow, it’s still a comfortable helmet that offers decent airflow and coverage. It's also pretty light making it a very worthy candidate as one of the best budget helmets on the market. Though its finish is indicative of its price.
