Giro introduces low price point MIPS helmets, Quarter and Dime.

MIPS is a system marketed specifically to address concern over rotational forces sustained in a crash, which is proven to be a large contributor toward TBI.

For those not familiar with Helmet Thread, there are those who claim that helmets do not help with and may even exacerbate rotational forces during a crash, leading to greater chance of TBI. Others say this is bunk, and the science regarding bicycle helmets and rotational force is not much help in settling the matter.

MIPS showed up in bicycle helmets a few years ago, but only in the more expensive ones, topping $200. With a $60 MSRP, Giro brings this system down to a more palatable price point. Not only that, but the form of the helmet -- more rounded, "skate" style vs. a more jagged, vented shape -- is also a nod toward a helmet with less downsides.
