Alpinestars S-M5 Solid Helmet - Black Matte (Medium)

The SM5 helmet is the culmination of more than five years of meticulous research, development, and testing. The team behind this product has scrutinized every possible aspect to engineer a helmet that not only prioritizes safety but also delivers optimal protection and comfort for the rider.

At the heart of the SM5 is a lightweight, thermo-injected shell that incorporates a special polymer blend. This unique material blend is engineered with varying degrees of thickness, strategically designed to provide the perfect balance of impact protection and lightweight construction. The five-density EPS liner ensures that the correct density is allocated to the appropriate areas, enhancing the helmet's ability to absorb impact effectively.

One of the standout features of the SM5 is its innovative design to protect the collarbone. The helmet features an engineered raised area with specialized padding, which is carefully crafted to reduce the forces transmitted to this vulnerable area in the event of a crash. This thoughtful design element sets the SM5 apart, providing an additional layer of protection for the rider.

Furthermore, the helmet boasts a patented visor release system that ensures the visor is released with the correct pre-determined amount of force, regardless of the angle of impact. This feature is designed to enhance the overall safety of the helmet, minimizing the risk of visor-related injuries.

Comfort and convenience are also prioritized in the SM5 design. The helmet is equipped with an emergency release system and removable cheek pads, allowing for safe and easy removal of the cheek pads while the helmet is still on the rider's head. This feature can prove invaluable in emergency situations, facilitating a quick and efficient helmet removal process.

To ensure optimal rider comfort, the SM5 features a removable comfort liner made with Silverplus treated anti-bacterial fabrics. These fabrics excel in moisture-wicking, effectively drawing perspiration away from the skin and keeping the rider cool and dry during extended rides. The anti-microbial liner is also removable and washable, ensuring long-lasting freshness and hygiene.

For added convenience, the helmet's cheek pads incorporate integrated hydration tube channels, allowing riders to stay hydrated without the need for cumbersome external tubing.

The soft textile chin strap, which measures 26mm in width, is wider than the certification requirements. This design choice prioritizes both optimal safety and rider comfort, providing a secure and comfortable fit.

In summary, the SM5 helmet is a testament to the team's dedication to engineering a product that combines advanced safety features, thoughtful design, and exceptional comfort. With its innovative construction, specialized protection elements, and attention to rider needs, the SM5 sets a new standard in the world of motorcycle helmets.
