Bell MX-9 Adventure MIPS Adult Off-Road Helmets
From the roughest singletrack to urban blacktop, the MX-9 Adventure MIPS gets you there safely in style. Weve 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.

Measuring the head is only a starting point for the entire sizing procedure. Due to varying shapes, heads that are apparently the same size when measured by a tape may not necessarily fit the same size helmet. A small metal tape measure or a cloth tape may be used to make your initial measurement. You can also use a string, which can then be laid against a measuring tape.
Measure the circumference of the head at a point approximately one inch above the eyebrows in front, and at a point in the back of the head that results in the largest possible measurement. Take several measurements. The largest measurement is the one you want to use.
