Brown pow is calling.

When it's time to ditch your responsibilities for the sweet solitude of rugged alpine trails and smooth-rolling forest loops, the Giro Fixture MIPS Helmet is a stellar choice with its lightweight In-Mold construction, MIPS technology, and well-ventilated design for comfort on long climbs and scorching-hot rides. To ensure a dialed fit, the Roc Loc Sport system adjusts to the exact shape of your head with the quick twist of its rear-mounted dial. 

Upgraded over the standard version, the Fixture MIPS employs a low-friction elastomeric liner that rotates independently around your head, should you suffer a nasty crash on the trail. Ultimately, this serves to dissipate rotational forces that would otherwise be transferred through the helmet, giving you added peace of mind when you're opening it up on high-speed descents, darting between trees along the trail, and rolling over steep rocks on bigger terrain.

  • Sleekly sculpted helmet for singletrack adventures
  • In-Mold construction keeps it lightweight, well-ventilated
  • MIPS technology dissipates rotational forces from angled impacts
  • Built-in visor shields your eyes from branches and harsh sunlight
  • Roc Loc Sport dial provides a micro-adjustable, head-wrapping fit

Unanswered Question

How large a head can this fit? My head is at least 7 5/8”.

finally a Bike helmet that fit me nice!

  • Familiarity: I've used it several times

I think this is the first bicycle helmet that I actually want to wear when I'm riding. The fitment on this particular model is perfect thanks to the MIPS tech, the colors are very vivid , I got one in matte lime for me and a matte frost for my girlfriend and both look good. very lite profile make this helmet fill like your not wearing it at all .

Great Fit, Color in photo isn't accurate

  • Fit: True to size

I was most nervous about the one size fits all detail but just like the other viewers say, it fits fine. My issue, and this is picky, is that the picture looks lime green, similar to the KALI PROTECTIVES
Viva Helmet, also sold on this site. This helmet is basically High Visibility yellow, and the visor IS Hi Vis yellow. They don't match.

Another awesome pick by the Gearheads!

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

You can dial in a great fit with this helmet, and it sits comfortably with the light weight. I also appreciate the sun visor much more than I anticipated!

Dad's Stoked!

  • Familiarity: I gave it as a gift but have feedback to share

Gifted this to my Dad for Christmas and he couldn't be happier! It's a great helmet at a price you can't beat that also has MIPS technology which should be vital to any biker! He put it on and could immediately dial in the fit with ease which was a fantastic bonus!

Great Helmet for the price

  • Familiarity: I've put it through the wringer

I bought one for my wife and me. For the price, you can't beat it. There are no other helmets that I found with MIPS for the price. Really comfortable fit. I usually fit between a large and medium. My wife fits in about a medium as well.

Great Value

    For this price point there is not a better helmet out there. Very adjustable and able to fit all head sizes. 10/10 would recommend!

    best helmet

    • Familiarity: I've used it several times

    Great helmet for mountain biking. Lightweight, comfortable, and the visor keeps sun out of my eyes.

    Price on Point

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

    For the price, this helmet cannot be beat! MIPS for $65! Not going to lie I was a little bit hesitant of the "one size", don't be mistaken this thing fits like a dream and has a huge range of adjustment.

    good helm

    • Familiarity: I gave it as a gift but have feedback to share

    very comfortable it adjusts for a fit and looks good MIPS at a great price..

    Low Cost MIPS

    • Familiarity: I've used it several times

    If you want a great fitting helmet that has MIPS you found it. It breaths well, it will keep your dome covered without sliding all over the place and it comes in all the colors to match your kit.

    A very nice helmet at a great price.

    • Familiarity: I've used it several times

    I ride A LOT and have three other Giro helmets. This helmet has 90% of bells and whistles of Giros top o’ line helmets at a phenomenal and fraction of the price. Light, cool, adjustable and comfortable.
