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. Ventilation is top-notch with numerous inlet and outlet ports connected with a series of airways that snake through the interior. The internal liner is an amalgamation of protective and comfort materials, and a multiple density inner liner absorbs impacts, while a MIPS-E2 liner protects against rotational energy. The Supertech M10 also features Alpinestars' proprietary A-Head system—an adjustable head frame that allows you to adjust how the helmet sits on the head, while soft EPP foam cushions the bottom lip of the helmet to help avoid collarbone injury in the event of a crash. Emergency removable cheek pads, along with a design prepared for the E-Ject helmet removal system make the Alpinestars MX Supertech M10 a protective motocross helmet that's filled to the brim with safety features. Key features: * Lightweight outer shell constructed from carbon fiber * Four shell sizes * Multiple density inner liner * Fitted with E-2 MIPS * Easy release peak * 2 peaks included: one regular and one super high * A-Head adjustable top pad height * Maximum ventilation with multiple intake and exhaust ports * Side shell shape coupled with soft EPP foam to prevent damage to collarbone in case of crash * Removable, emergency release cheek pads with 3-D contoured foam * Removable anti-bacterial and hydrophobic comfort liner * Hydration prepared * E-Ject prepared * DOT and ECE approved

Engineered for Enduro, MX, and off-road riding, the Alpinestars MX SM3 helmets integrates advanced technologies and innovations designed to enhance ease of use, comfort, and most importantly impact protection. With an advanced shell construction, the SM3 helmets 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. Maximized ventilation and high levels of heat transfer exchange, thanks to 10 inlets and seven exhaust ports. Alpinestars patented low-friction coating is applied to the inner part of the main EPS liner to reduce the rotational acceleration forces that can result from certain oblique impacts. This layer essentially acts as a slip plane to mimic the brain's own low-friction cerebrospinal fluid, which is the body's natural defense against oblique impacts. 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. The SM3 helmets are available in a range of sizes and color options. Order the helmet in size you'd prefer. Key features: * The SM3 helmet conforms to both DOT certification and ECE 2206 homologation for use worldwide * 5 EPS inner parts with 4 densities to effectively manage volume and impact performance * Removeable comfort liner is constructed using recycled materials for a lower carbon footprint * The inner and outer surfaces are engineered to minimize the effects of oblique impacts * The fit can be tailored to the rider's head, thanks to the helmet's crown and cheek pads, which are available as genuine spare parts in different thicknesses * Hydration tube channels are integrated into the helmet's cheek pads for convenience and performance * 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 * Soft textile chin strap is 25mm for optimal safety and rider comfort * Stainless steel D-rings ensure a tight and secure fit
