Alpinestars MX SM5 helmets provide riders with a helmet that is safe and purposefully designed to deliver optimal protection and comfort. The lightweight SM5s feature a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and lightweight, while the 5-density EPS liner ensures the correct density in the correct area for enhanced impact absorption. Alpinestars MX SM5 helmets are available in a range of sizes from X-Small to 2X-Large and offered in a variety of solid colors and graphics to satisfy your personal style. Key features and highlights: * Lightweight, impact-resistant thermoplastic outer shell * An engineered raised area with padding effectively reduces the forces transmitted to the collarbone * A patented visor release system that ensures the visor is released with the correct pre-determined amount of force, irrespective of the angle of impact * Revised the Medium, Large, X-Large, and 2X-Large lower shell volume to be around 3 percent wider to make the helmet easier to put on and take off, where the increase in helmet volume has also improved the impact management performance which is now 44 percent lower than the regular-speed threshold * For the new ECE 22.06 standard, the SM5 achieves a 44 percent better regular-speed impact rating compared to the current 33 percent figure, as well as a 32 percent better low-speed, and 31 percent better high-speed linear impact score than the prevailing standard * Redesigned chin bar profile--the base area has been specifically sculpted to give a relief section, raised to clear the collarbone, with a new softer EPS liner which extends beyond the helmet shell itself, and is covered by a more flexible rubber compound providing a reduced chance of any sort of collarbone injury * Maximized ventilation and high levels of heat transfer exchange thanks to multi-air inlets and exhaust ports * The visor has been designed to direct air into the ports for enhanced airflow

Alpinestars MX Supertech M10 helmets feature a lightweight carbon fiber shell that is offered in several different shell sizes—and Alpinestars' provides two peaks with two different angles, depending on the rider's preference. The visor design of the M10 is also an integral part of the ventilation system as it is profiled to direct airflow, acting as a channel to concentrate and smooth the flow into the shell.

Anatomically engineered and profiled specifically for youth and younger riders, the all-new SM3 youth helmets from Alpinestars MX are optimized for motocross, Enduro and off-road use, and features a whole raft of technologies and innovations taken from Alpinestars range of adult helmets to deliver the optimal blend of performance, protection and comfort. The youth medium (YM) and youth large (YL) helmet sizes share the same EPS size, which allows riders with a 'YM' size to initially buy a 'YM' helmet, and then configure it to a youth large size as they grow via the crown and cheek pad spare parts. The youth small (YS) helmets have a smaller EPS size and can be customized only via the cheek pads—Alpinestars extensive research has shown that the kids that wear an 'YS' size helmet are very small, typically 3 to 4 years old, and therefore they require a dedicated helmet fit. Instilling a safety-first mindset is crucial for young riders, Alpinestars MX offers motocross safety gear to support your child's journey and understands the sport's demands. The SM3 youth helmets are available in a variety of styles, in solid colors or with graphic designs displaying Alpinestars MX logos. Key features of the youth helmet: * Helmet features a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and light weight * Separate versions of the shells for DOT and ECE requirements; the DOT certified version of the helmet's inner shell is constructed with a composite fiber assembled between the outer shell and the EPS liner for maximum protection against impacts—the SM3 helmet conforms to both DOT certification and ECE 2206 homologation for use worldwide * The fit can be tailored to the rider's head thanks to the helmet's crown and cheek pads, which are available as spare parts in different thicknesses * Equipped with an Emergency Release System and removable cheek pads to permit the safe and easy removal of the cheek pads while the helmet is still on, while the 3D contoured foam ensures rider comfort * Stainless steel D-rings ensure a tight and secure fit * Multiple density inner liner ensures the helmet is equipped with the correct density in the correct area for enhanced impact absorption, while also helping to reduce overall weight * Inner and outer surfaces are engineered to minimize the effects of oblique impacts * Maximized ventilation and high levels of heat transfer exchange, thanks to ten inlets and seven exhaust ports * The visor has been designed to direct air into the ports for enhanced airflow * Patented visor release system ensures the visor is released with the correct pre-determined amount of force, effectively reducing the forces on the rider's neck during an impact * Comfort liner is constructed using recycled materials for a lower carbon footprint * Hydration tube channels are integrated into the helmet's cheek pads for convenience and performance (hydration system sold separately) * Soft textile chin strap is 25mm for optimal safety and rider comfort
