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\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eFeatures\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eSHELL: Lightweight polymer shell\u003cbr\u003e3-IN-1 SAFETY SYSTEM: When combined with the impact foam, 360° Turbine Technology offers a unique 3-in-1 safety system by protecting against low-speed impacts, high-speed impacts, and rotational forces.\u003cbr\u003eIMPACT FOAM: In-molded EPS + EPO impact foam for superior energy absorption\u003cbr\u003eTURBINES: 360° Turbine Technology\u003cbr\u003e• Rotation protection: The optimally designed turbine discs enable the helmet to move slightly on the head upon impact, helping to reduce peak acceleration to the head \u0026amp; brain.\u003cbr\u003e• Low impact protection: The special energy absorbing material in the turbines absorbs low impact energy associated with concussion.\u003cbr\u003eVENTILATION: 18 vents effective even at low speeds\u003cbr\u003eLINER: Moisture wicking, breathable, anti-odor and washable inner liner\u003cbr\u003eFIT SYSTEM: Flat Lock Strap divider and fit system developed for custom fit, ease, and comfort\u003cbr\u003eCLOSURE: Fidlock magnetic closure system\u003cbr\u003eVISOR: Adjustable visor with breakaway function for rotational impact force reduction\u003cbr\u003eOTHER FEATURES: Sunglasses dock port for easy, secure storage • Soft touch and moisture wicking chin straps • Plastic-free packaging\u003cbr\u003eWEIGHT: From 430g (0.95 lbs)\u003c\/span\u003e\u003c\/p\u003e","brand":"Leatt","offers":[{"title":"Medium \/ Brushed Grey","offer_id":48098867577076,"sku":"1024120351","price":209.97,"currency_code":"USD","in_stock":true},{"title":"Large \/ Brushed Grey","offer_id":48098867609844,"sku":"1024120352","price":209.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/5364\/files\/Leatt_2026_HelmetMTB_4.0All-MTN_Brushed_Right_1024120350_84a3a482-75eb-4f7f-bef6-a8f8f8dd1dff.webp?v=1777400680","url":"https:\/\/gravitycoalition.com\/products\/leatt-allmtn-4-0-bike-helmet","provider":"Gravity Coalition","version":"1.0","type":"link"}
