Alpinestars Supertech M10 vs Alpinestars SM7 Helmet

The Supertech M10 is Alpinestars' top-tier off-road helmet: a 3K carbon shell, MIPS, four shell sizes and roughly 1,260 g in size M. The SM7 is the step below, with a fiberglass, carbon and Aramid composite shell, three shell sizes and about 1,280 g (ECE). Both share the A-Head fitment system, the visor release system and the collarbone relief chin bar. Buy the M10 if you race or ride hard and want the lightest, most ventilated option; buy the SM7 if you want most of that protection for less and ride mostly trail and enduro.

• Choose the Supertech M10 if you want the lightest, most ventilated Alpinestars off-road helmet with MIPS and a carbon shell.
• Choose the SM7 if you want a certified ECE 22.06 and DOT off-road helmet with the same fit system and visor release at a lower tier.
