Packed with innovations and advanced technologies, the SM3 focuses on user-friendliness, exceptional comfort, and superior impact performance to keep you safe on every ride.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThis helmet features a thermo-injected shell constructed from a special polymer blend. This carefully engineered design incorporates varying degrees of thickness to achieve the optimal balance between lightweight construction and robust impact protection. The innovative, patented low-friction coating applied to the inner EPS liner minimizes rotational acceleration forces resulting from oblique impacts. This slip plane mimics the brain's natural cerebrospinal fluid, providing an additional layer of defense against rotational injuries. The patented visor release system ensures the visor detaches with the correct pre-determined force, mitigating the forces transferred to the neck during an impact. With 10 intake vents and 7 exhaust ports, the helmet provides maximum ventilation, facilitating efficient heat transfer and keeping you cool under pressure. Stay protected and comfortable with the Alpinestars SM3 Radium helmet.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eOptimized for MX, Enduro, and off-road use, providing advanced protection for demanding riding conditions.\u003c\/li\u003e\n  \u003cli\u003eThermo-injected shell with a special polymer blend balances lightweight design and high-impact resistance.\u003c\/li\u003e\n  \u003cli\u003ePatented low-friction coating inside the EPS liner reduces rotational acceleration forces during impacts.\u003c\/li\u003e\n  \u003cli\u003eVisor release system ensures detachment at a pre-determined force, reducing neck strain during crashes.\u003c\/li\u003e\n  \u003cli\u003eExtensive ventilation system with 10 inlets and 7 exhaust ports maximizes airflow and heat exchange.\u003c\/li\u003e\n  \u003cli\u003eUnisex design suitable for a wide range of riders.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eBrand: Alpinestars\u003c\/li\u003e\n  \u003cli\u003eType: Off-Road, MX\u003c\/li\u003e\n  \u003cli\u003eShell Material: ABS\u003c\/li\u003e\n  \u003cli\u003eColor\/Finish: Black, Gray, White\u003c\/li\u003e\n  \u003cli\u003eFinish: Gloss\u003c\/li\u003e\n  \u003cli\u003eVented: Yes\u003c\/li\u003e\n  \u003cli\u003eGender: Unisex\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eImportant to know\u003c\/h2\u003e\n\u003cp\u003eNo additional information provided.\u003c\/p\u003e","brand":"Alpinestars","offers":[{"title":"XS","offer_id":53785582240074,"sku":"01109153","price":241.95,"currency_code":"EUR","in_stock":true},{"title":"S","offer_id":53785582272842,"sku":"01109154","price":241.95,"currency_code":"EUR","in_stock":true},{"title":"M","offer_id":53785582305610,"sku":"01109155","price":241.95,"currency_code":"EUR","in_stock":true},{"title":"L","offer_id":53785582338378,"sku":"01109156","price":241.95,"currency_code":"EUR","in_stock":true},{"title":"XL","offer_id":53785582371146,"sku":"01109157","price":241.95,"currency_code":"EUR","in_stock":true},{"title":"2XL","offer_id":53785582403914,"sku":"01109158","price":241.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/7e9ba3bdaf636fecf5cd9906b1073e56.webp?v=1768237392","url":"https:\/\/partsdenmark.de\/products\/alpinestars-sm3-radium-off-road-helmet","provider":"Parts Denmark","version":"1.0","type":"link"}
