A Ball-and-Socket Helmet?! Giro's New Manifest Spherical

Giro's latest helmet features ALL of the bells and whistles, claiming the top spot in their MTB lineup.

Vital Review

Brand new halo products don't come around often, and when they do it's worth taking note. The Manifest Spherical represents countless hours of design and thorough vetting in the Dome – Giro and Bell's widely regarded test lab. It has a two-piece EPS liner with progressive layering to better manage high- and low-speed impacts. The two layers can rotate around one another like a ball and socket, something not often seen before. It also vents incredibly well, providing 7% better cooling than their proven Montaro MIPS lid.

Join Zach Petersen in the video above for a look at what makes it stand out and some initial impressions. Although it's on the pricey side, he's been thoroughly impressed by the Manifest Spherical so far.

When not racing he's smashing out big backcountry days in the Sierra Nevada, pushing dirt around the forest with a McLeod, and keeping the stoke high with Trail Peek.

Isn't that just another version of a MIPS system? I wish they'ed go into more about what's in between the two layers. And even if I still had a job, I couldn't pay that much.

Not stoked about the styling. It looks like you're wearing a helmet on your helmet. I guess technically you are?
