Why We Like The Manifest Spherical MIPS Helmet

The Manifest Spherical Helmet premieres Giro's revolutionary Spherical Technology for enhanced safety on the trail. Powered by MIPS, Spherical Technology utilizes a similar slip-plane design as MIPS for greater impact absorption at angular crashes, except Spherical opts for two layers of foam with a slip-plane between the two, instead of a plastic liner. This redirects impact energy by rotating the exterior liner independently from the interior liner, and it enables greater ventilation for a cooler time on the trail as well as a safer one.

Giro geared the Manifest for sweaty riding in hot weather with nineteen Wind Tunnel vents, all amplified thanks to Aura's reinforcement around the arch. XT2 padding provides a comfortable fit, and the lining wicks sweat, dries quickly, and reduces any unwanted odors. Giro also redesigned the Roc Loc Trail Air Fit System for enhanced durability and dynamic strength. The visor adjusts to accommodate eyewear and goggles, and Giro included grippers to make sure either stay in place.

Comfortable and cool

Great helmet. Comfortable so far with really good ventilation, however I have not used it for a full summer yet. The Giro Manifest Spherical looks good and has very good adjustability. No complaints so far.

Best fitting and comfortable helmet

I ordered this because I wanted a new helmet. I chose the medium Matte Ano Orange. It turned out to be the nicest, best fitting helmet I've owned. I worried about setting up my helmet mounted mirror because of the visor (which I really like), but it worked out perfectly. The magnetic fasteners on the chin strap take some practice to get used to.

Awesome Helmet!

I've used it several times

Great helmet. Comfortable, looks great, and I'm sure it will protect my noggin' if I ever need it to do so. Only gripe is the knob at the back can be hard to turn.

Great mtb helmet

I've used it several times

Quality is amazing and air vents are generous. It's saved my grape a couple of times. The only thing I would have liked is better sweat management. The inside pad doesn't do a very good job at keeping it out of your eyes.

So comfortable

I've used it once or twice and have initial impressions

I absolutely love this helmet. I understand that many people consider it expensive, but when I see bib shorts going for 180 to 280, I think spending 250 on something that will save your life - or quality of life - to be pretty reasonable. Mag closure is super easy once you figure it out. You feel like you're pressing buttons to release it, but really you're just sliding the magnet apart. Once you realize that, it will stop messing with your head! The fit is SO nice. I can see why it's often rated as the most comfortable helmet. Zero pressure points, zero wiggle. I'm so happy I bought it!

This helmet fits great it is very stylish. I really like the mag buckle as it?s easy to attach and detach. The vents are great for getting air over the noggin It?s definitely on the pricey side but you get what you pay for.
