The M5 Solar helmet is made from a special thermo-injected polymer that makes it lightweight and impact resistant, offering increased structural strength and outer shell uniformity.

• Constructed from a special thermo-injected polymer,
• light and impact resistant, it allows to obtain a helmet
• significantly lighter, with increased structural strength and uniformity of the
• and uniformity of the outer shell in two sizes
• The inner shell features an advanced multi-density EPS construction
• for optimal shock absorption performance in three sizes
• Includes two designs for impact energy management,
• including a resin-coated inner shell surface that significantly
• significantly improves impact resistance and reduces linear acceleration values and a
• linear acceleration values and an elastic seal to connect the helmet's inner shell
• helmet inner shell and comfort liner for free movement in the event of a
• free movement in the event of a collision with an oblique impact, thus distributing the
• energy forces of an impact, reducing rotational acceleration
• Uses the Alpinestars Emergency Release System (ERS) which
• consists of removable cheek pads that allow medical professionals
• medical professionals/accident responders to remove the helmet
• remove the helmet easily, quickly and safely
• The ERS features easy-to-locate pull tabs for quick release of the cheek pads, minimizing
• cheek pads, minimizing the risk of further injury
• Includes a multi-angle, quick-release visor system that is flush with the
