Engineered for MX, Enduro, and off-road riding, the SM3 Helmet integrates advanced technologies and innovations designed to enhance ease of use, comfort, and impact protection.
Key Features
- Ventilation: Maximized ventilation and high levels of heat transfer exchange thanks to 10 inlets and seven exhaust ports.
- Rotational Acceleration Force Protection: 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.
- Visor Release: 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.
Construction
- 5 EPS inner parts with 4 densities to effectively manage volume and impact perfromance.
- Hydration tube channels are integrated into the helmet’s cheek pads for convenience and performance.
- Comfort liner is constructed using recycled materials for a lower carbon footprint.
- 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.
Protection
- The inner and outer surfaces are engineered to minimize the effects of oblique impacts.
- 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.
- The SM3 helmet conforms to both DOT certification and ECE 2206 homologation for use worldwide.

Engaging story with beautiful art
Of all the Manga Classics artists, SunNeko Lee is by far my favorite. Her work perfectly accompanies Hawthorne's words, which have been expertly adapted to Manga by Crystal Chan. As an added bonus, there are a couple well timed moments of levity/humor in the artwork to go along with this otherwise somber story. I finished this book in three days because I couldn't put it down - an adaptation worth viewing for manga and novel enthusiasts alike.

Awesome introduction of classics to elementary children
We borrowed a bunch of Manga Classics from the library and The Scarlet Letter and Les Mis were my Grade 2 daughter's favorites. I read the books with them to discuss the faith and character issues. Included in the back are the artist and the writer's explanation on how they break down the novel into a manga format and translated the original ideas into drawings. What I love from these Manga Classics is that they didn't rewrite the content but pulled actual passages from the original text and added minor changes to make the storyline flow.
