Alpinestars Supertech S-M10 Carbon San Diego Helmet

Rome wasn't built in a day. Don't expect a sprawling city that can be considered the first ever metropolis or the capital of the world to be made lickety split.  Similarly, Alpinestars' first foray into off-road motorcycle helmets took years of development, but the pay-off is a high end carbon fiber helmet with state of the art features and materials.

The Alpinestars Supertech S-M10 Carbon helmet uses a lightweight carbon fiber shell that comes in 4 different shell sizes. Its visor release system holds the visor/peak securely, but releases in the event of impact. Alpinestars provides 2 peaks with 2 different angles depending on the rider's preference. 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. A multiple density inner liner absorbs impacts while a MIPS-E2 liner protects against rotational energy. Alpinestars' proprietary A-Head system is an adjustable head frame that allows you to adjust how the helmet sits on the head. 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 Supertech S-M10 Carbon Helmet a protective motocross helmet filled to the brim with safety features. 

This isn't a fast food burger that has been sitting under a heat lamp. This type of refinement has to be made from the ground up. The feature packed Alpinestars Supertech S-M10 Carbon Helmet is a Michelin starred restaurant's testing menu compared to lower end helmets.
