Bell Sixer MIPS Helmet The trail helmet that disappears when you wear it Sketchy rock drops, mach-speed alpine forest tunnels, slippery river rocks - trail riding means a lot of different things, and the Bell Sixer MIPS is built to handle all of them. A full hard shell, Dual Flow Ventilation(TM), and Progressive Layering(TM) dual-density EPS liner put genuine protection and comfort at the core, while Mips Evolve(R) integrates the slip plane directly into the Float Fit Race(TM) retention system for a closer-to-the-head fit that's lighter and better ventilated than traditional Mips. A 4-position adjustable visor, integrated breakaway camera mount, Goggle Gripper, and Sweat Guide(TM) make every detail work for you on the trail - so the only sweating you have to think about is your own.
