Giro Ratio Mips Helmet 2026

The Goggle

The Giro Ratio MIPS Helmet is the lid we hand to skiers and riders who want one helmet that does everything right without any fuss. It's built for the person who covers the whole mountain in a day - groomers before lunch, a lap through the trees after, maybe a stop for hot chocolate (or beer) before the last chair.

What Sets It Apart

Inside the shell, Giro built in their Integrated Mips system - a low-friction layer that lets the helmet shift slightly on your head during certain angled impacts, cutting down the rotational force that reaches your brain. You won't notice it on a normal day of skiing, and that's kind of the point. You only feel it working on the one day you actually need it.

On top of that, the Thermostat Control vent system uses a low-profile button you can hit with a gloved hand - open it up on a warm spring afternoon when the snow's going soft, close it down when the wind picks up on a cold chairlift. And the Stack Vent Technology lines the vents up with your goggle frame, so air actually moves across the lens instead of sitting there and fogging up your view on a humid Pennsylvania day.

Fit & Safety

The In Form Fit System is a dial at the back of the helmet that gives you up to 6cm of adjustment. Dial it down snug over a thin buff, or open it up to fit over a thicker beanie on the really cold mornings. It's a quick turn even with gloves on, and it holds once you've got it set.

Why Willis

We've been fitting Pittsburgh skiers and riders since 1970, and a helmet is one of the few things we always tell people to try on in person before buying. Stop into any of our three locations and our staff will get you into the right size and walk you through the dial and vents before you ever get in a lift line.
