Constructed with a lightweight yet durable composite shell, it features an aerodynamic profile that minimizes drag and enhances stability at high speeds. The smooth, streamlined design eliminates external channels and protrusions, reducing impact load points and maintaining the helmet's structural integrity. Its curvature promotes reduced friction upon impact, facilitating energy deflection and transfer to protect the rider's head, neck, and spinal column effectively. This helmet incorporates 20 ventilation ports, including 13 intake and 7 exhaust vents, ensuring optimal airflow to keep the rider cool during intense off-road activities. The ventilation system is complemented by removable, washable liners treated with antimicrobial fabrics for hygiene and comfort. The fit is highly customizable with interchangeable cheek pads available in various thicknesses, allowing for a tailored fit across all sizes. The helmet features a cutaway section on the left side to seamlessly house communication systems, with earphone recesses on both sides for speakers, making it ideal for riders who need to stay connected on the trail. Safety is further enhanced by the visor detachment system, which allows the visor to automatically release under impact energies exceeding 15 Joules, preventing injury from visor-related impact forces. The inclusion of Alpinestars PLASMA technology in the side pads significantly reduces energy transfer during shocks, providing enhanced impact absorption where it is most critical. The crown and neck pads are elastically connected to better manage oblique impacts, and the top pad is adjustable in height via the A-head system for a personalized fit. The chin strap features a 25 mm nylon strap with stainless steel DD rings and removable covers for easy cleaning. Additionally, the helmet is compatible with hydration systems, with integrated channels on both sides. The design emphasizes safety, ventilation, and comfort, making the Alpinestars SM7 an ideal choice for demanding off-road riders who require high-performance head protection.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eAerodynamic profile with streamlined shell design for stability and impact integrity\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eUltra-ventilated with 20 ports (13 intake, 7 exhaust) for optimal airflow\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRemovable, washable antimicrobial liners for hygiene and comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCustomizable fit with exchangeable cheek pads in all sizes\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCommunication system compatible with cutaway EPS section and earphone recesses\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eVisor detachment system designed to release upon impact exceeding 15 Joules for safety\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIntegrated PLASMA technology in side pads for superior shock absorption\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eElastically connected crown and neck pads for enhanced impact management\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjustable top pad via A-head system for personalized fit\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eChin strap with 25 mm nylon strap, stainless steel DD rings, and removable covers\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIntegrated channels for hydration systems on both sides\u003c\/li\u003e\u003c\/ul\u003e","brand":"ALPINESTARS","offers":[{"title":"Default Title","offer_id":45186782855363,"sku":"01109282","price":519.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/6052\/2435\/files\/5572691.png?v=1779216089","url":"https:\/\/kellymotorsport.com\/products\/alpinestars-sm7-helmet-core-matte-orange-blue-large-part-8301826-408-l","provider":"Kelly Motorsports","version":"1.0","type":"link"}
