Alpinestars Supertech M10 Squad LE 23 sku-3664563269

The Alpinestars Supertech M10 Squad LE 23 is an XL motocross helmet in Dark Brown and Gold, listed under Dirt Bike Gear as sku-3664563269. Developed and tested over more than five years, the Supertech M10 debuted at Anaheim Supercross in January 2018. Alpinestars designed it around protection, ventilation, comfort, and lower weight.

Its smooth shell has no external channels that could become load points in an impact; the curved surface is intended to reduce friction and help deflect impact forces. The opening fits a range of goggles, and shell vents and ducts are positioned to move air over and around the rider's head. Each fit size has its own shell size.

The components and construction were assessed for weight, strength, and energy absorption. The M-10 weighs 1240g in Medium under ECE specifications and 1340g in Medium under DOT specifications. Alpinestars says reduced weight distribution may lessen effort in the neck, shoulders, and back. Ventilation ducting was developed using heat mapping tests.
