Fitness rides, adventure rides, family rides around the neighborhood. Its new rounded shape looks and feels smaller. But with its quality in-mold polycarbonate shell construction and easy, approachable style, the new Blitz is an all-around performer that gives you lots of options. This model offers the addition of MIPS (Multi-Directional Impact Protection System), which is a low friction layer between the shell and the liner which allows the helmet to slide relative to the head in certain crash scenarios. Large vents keep you cool on hot days. The one-size-fits-all ErgoDial Fit System allows for one-handed adjustment-- just press a button and turn the dial, simple as that. And there's a snap-in removable visor that ensures you'll see what's ahead in bright trail conditions. That's the Bell Blitz MTB helmet. Totally comfortable, totally cool.
