Stacked to the brim.

The Bell Sixer MIPS Helmet is stacked with just about every feature the aggressive trail rider or enduro racer could wish for, from its MIPS technology to strap grippers that keep your goggles firmly in place. As the premier helmet in Bell's line for trail and enduro, the Sixer MIPS is especially lightweight and well ventilated, thanks to In-Mold construction reducing its overall bulk and allowing massive vents to rapidly disperse heat. To ensure a secure fit, you'll enjoy the twist-to-tighten convenience of Bell's Float Fit system located along the backside.

MIPS technology gives you peace of mind by dissipating forces that happen when you hit an object at an oblique angle, which is bound to happen when you grab too much front brake or perilously fly over the bars on a technical section. Another beneficial feature, the 4-position visor keeps overhanging branches from poking your eyes and harsh sunlight from washing out vision. Moreover, it's boasting a breakaway action-camera mount for capturing all the action on the trail.

Best helmet I have owned. Cool, keeps sweat away from eyes and stays on head.

Unanswered Question

For what shape head is this helmet designed? I have an older Bell Super 2 MIPS helmet that fits me well (oval head shape), but I tried a Bell Catalyst that fit me poorly because it seems to be designed for around head.

Great Helmet~

It's comfortable and keeps the sweat out of my eyes. If you want a good fitting helmet that offers plenty of protection and ventilation, I recommend this helmet.

another helmet home run from Bell/Giro

Style, fit, breathability, value all great on another quality offering. I ride enough and bash enough helmets I'm buying a new one at least yearly. Having tried most of the major brands, I keep waffling back and forth between the Bell and Giro helmets. If you liked the Bell Super hemelts you'll like this. If you like the Giro Montaro, you'll like this. Fit is better for me than Fox and breathability is better than Smith (and I dig the style of both of those helmets). There are a lot of great helmets out there. Bell Sixer is one of them IMO.

We have a winner!

I have always been a big fan of bell/giro helmets. This one just upped my support level even more. First off, the fit is excellent. I have always been picky as far as helmet shape, especially with MIPS, and this one fits like a glove (Helmet??)Bell took it even further with their new full float helmet system, that works similar to MIPS with the helmet motion, but the full float gives it even better movement, all while fitting extremely well, and secure. The ventilation is excellent in this helmet also, with plenty of inlet vents, and large exhaust vents out to back to keep that air moving. The multi position visor is great, and can accommodate goggles for climbing and keeping the fog down. A new cool feature they have done is with the padding. At the front of the helmet, the padding has a small extended piece in the center of the forehead. This is designed as a point for sweat to flow to, and if it drips, it drips away from your face, rather than all over your face and eyes. I was skeptical about it at first, but it works surprisingly great. Two thumbs up from Bell. If you need a new helmet, this is definitely a top contender in my book.
