Built with in-molded EPS + EPO impact foam for enhanced energy absorption, it is certified to ASTM F1952-15 (downhill MTB) and NTA 8776 (e-bikes going up to 45km\/h \/ 28 mph) standards—making it an ideal choice for aggressive rides and e-MTB adventures. Leatt’s 360° Turbine Technology helps reduce rotational forces and absorb low-speed impact energy, while the impact foam provides high-speed impact protection—working together as a 3-in-1 safety system. The modern profile meets the highest safety standards,  yet it remains lightweight and breathable, with a moisture-wicking liner to manage sweat. A Fidlock magnetic buckle makes for easy one-handed closure, and the adjustable breakaway visor adds another layer of protection in a crash. With a secure fit system, integrated eyewear dock, and sleek design, the AllMtn 4.0 is built for riders pushing the limits.\u003c\/p\u003e","brand":"Leatt","offers":[{"title":"Stealth Black\/Grey \/ S","offer_id":68025457082664,"sku":"1023015150","price":153.3,"currency_code":"USD","in_stock":true},{"title":"Stealth Black\/Grey \/ M","offer_id":68025457049896,"sku":"1023015151","price":153.3,"currency_code":"USD","in_stock":true},{"title":"Stealth Black\/Grey \/ L","offer_id":68025457017128,"sku":"1023015152","price":153.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0689\/8876\/4207\/files\/Leatt_2026_HelmetMTB_4.0All-MTN_Stealth_ISO_1023015150_b20e005a-d921-4b1a-8b79-dd292efc668d.png?v=1792569728","url":"https:\/\/us.leatt.com\/products\/year-end-helmet-mtb-allmtn-4-0-stealth-black-grey","provider":"Leatt USA","version":"1.0","type":"link"}
