Why We Like The Fixture MIPS Helmet

When it's time to ditch our responsibilities for the sweet solitude of rugged alpine trails and smooth-rolling forest loops, we find that the Giro Fixture MIPS Helmet is a stellar choice with its lightweight In-Mold construction, MIPS technology, and well-ventilated design that keeps us comfortable on long climbs and mid-summer 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.

  • 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

Cheap plastic junk

I've used it several times
Size Bought
5` 10"
155 lbs

The knob to tighten the helmet broke off, rendering the whole thing useless. The entire harness that fits around your head comes down to a 1/2 cm diameter piece of plastic at the knob. Spend more, don't bother with these cheap helmets. The intent is clearly not to make the product have longevity. To be fair, it worked well until it completely failed spontaneously.

Very good Protection without Distraction

I've put it through the wringer
True to size

The helmet fits well--isn't heavy, doesn't pinch, and has good ventilation. It adjusts easily with the dial at the back. The color and sizing were accurate. The inside lining does a good job of absorbing sweat on the longer, hotter rides.

Such a Steal!

I've used it several times
True to size

I just got my first mountain bike, and I gotta say I was doing some groaning and moaning about putting in the money for yet another helmet for yet another sport. I took a flyer on this because it was the cheapest one available with MIPS. I was pretty skeptical of the one-size idea, but man - this thing rules. The fit really does seem to be magic. It's definitely closer to an L shell (maybe more?) but it doesn't move at all after I dialed it in. The vents seem huge compared to my other helmets. The visor also works super well; I'm more used to little road bike visors that don't a whole lot, but I've ridden in this without sunglasses (oops) and it protected me pretty dang well from the sun, even if it couldn't do much about dust. Super solid helmet, and that price is hard to beat!


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

finally a Bike helmet that fit me nice!

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

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!

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!

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

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!

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

Price on Point

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.

Low Cost MIPS

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.

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.
