Bell MX-9 Adventure Mips Mesa Helmet
From the roughest singletrack to urban blacktop, the MX-9 Adventure Mips gets you there safely in style. We’ve taken our MX-9 and added even more capability with an integrated anti-fog, anti-scratch clear faceshield. The shield flips up and leaves enough room for goggles in extreme conditions, or it can be removed completely. Conversely, the adjustable visor can be removed for a stealth street look. Mips protection, Velocity Flow ventilation, and a removable, washable, anti-microbial liner round out a highly adaptable package. *The Marauder Blackout colorway ships with a second dark smoke shield. Availability, certification, color, and pricing may vary per region. If outside of the USA, please check with your authorized local dealer for more information.

This sizing chart is based on information provided to us by Bell Helmets and is subject to change without notice, although we will do our very best to keep it up to date. We recommend that you measure your head by wrapping a cloth tape measure around your head about 1 inch or 2.5 cm above your eyebrows, which should be the largest portion of your head. Choose the helmet that is closest to your measured head size. If you fall between two sizes, choose the smaller of the two. You want a helmet to fit snug without being uncomfortable.
