Giro Tenet Mips Helmet 2026

The Helmet

Giro built the Tenet MIPS for skiers and riders who want one helmet that handles a full day on the hill without babying it. The upper is a hard shell, tough enough to shrug off the scrapes that come from tossing your gear in the trunk or leaning it against a lift tower, and the lower half is in-molded to keep weight down where it matters most - around your ears and the back of your head. You get durability up top and a lighter feel lower down, which is a nice trade-off instead of picking one or the other. Browse the rest of our helmets if you want to compare a few side by side before deciding.

What Sets It Apart

MIPS is in there, and it does its job quietly - a low-friction layer that lets the helmet shift slightly on impact so rotational force doesn't transfer straight to your brain. You won't notice it's there until the day you're glad it was.

The Thermostat Control vent adjustment is the feature we find ourselves pointing out most. It's a low-profile button on the outside of the shell - no reaching under the helmet, no fumbling with a slider buried in your hair. Push it open on a warm spring afternoon when the sun's cooking the groomers, push it closed when a cold front rolls through and you're standing in the lift line wondering if you dressed warm enough.

The Ionic+ fleece lining uses actual silver thread woven into the fabric, and it keeps the inside of your helmet from turning into something you don't want to put back on your head after three days of hard skiing. It manages moisture and keeps odor from building up permanently, not just masking it for a run or two.

Fit & Safety

The In Form 2 Fit System gives you up to 6 cm of adjustment through a rear dial, and it's built to turn easily even with ski gloves on - which sounds like a small thing until you're standing in 20 degree wind trying to tighten your helmet with bare fingers. Dial it snug at the lodge, then loosen it a notch if you're wearing a thinner beanie underneath on a warmer day.

One thing worth knowing upfront: this is an adult helmet built around adult head sizes, so if you're shopping for a kid, you'll want to look at a youth-specific model instead. It's not a fit for smaller heads, and that's fine - Giro makes plenty of other helmets that are.

Why Willis

We've been fitting Pittsburgh skiers and riders since 1970, and helmet fit is one thing we won't rush you through. Stop into any of our three locations and we'll get the dial adjusted, check the strap, and make sure it sits right before you ever hit our local hills.
