Bought this during the bike sale at the recommendation of a friend who explained the great safety features that went into the design of this helmet. Doesn ’ t hurt that it ’s also pretty good looking. The removable visor is a nice touch that offers two different look options.

I saw an expert review rating this helmet very high. I wanted to get the technologically advanced MIPS feature which it has. The helmet is very lightweight, has a lot of vents to keep me cooler on long rides in summer heat. I passed up the dark red and black helmet that would have looked great with my bike in order to get the bright white color that would be more visible to motorists. It is lighter weight than the good Bell helmet I replaced, and the straps are lighter, more flexible material. Very pleased with this helmet.

5 DannoBikes
This is both my first Giro brand helmet and my first MIPS technology helmet. I like how Giro has the side straps set already so that's two less buckles to adjust and loosen on their own. Coming from Bell helmets I had to get used to adjusting the straps by pulling to center them each wear no biggie for better comfort. Speaking of comfort the dial to tighten in the back is much better than Bell helmets. The MIPS technology allows the helmet to move slightly while staying right to your head to reduce injury in a collision. As a former racer, courier, and bicycle commuter I can feel how that would help. I hope I never need it Overall the best helmet I 've ever owned.

[ Absolutely love this helmet. Tried hard to go with either the POC Tectal or Kortal prior to buying this one and I 'm so glad I did! It fits like a glove and I totally forget I 'm wearing it while riding. It's by far not as bulky as the POC helmets and it also feels at least subjectively lighter. Love the color schemes as well and can not praise the fit of this helmet enough. Sizing is spot on and the magnetic buckle is also a plus.

[ I was riding a black diamond section of a trail and I lost my balance and fell about three feet off the trail along with my bike and hit my head really hard on large rock.

Christmas gift because my daughter started riding her bike again after college, and riding without one is n't an option. I 've been riding for over 40 years, but she rides recreationally so did n't need to spend$ 150+ for a safe helmet. This helmet was less than half that, had latest MIPS tech, and was sized for women with wide adjustability. You can find great equipment across many budget ranges at Dick's. Glad I gave it a go.

Adjustable bike helmets are versatile and can be used for various cycling activities, including road biking, mountain biking, and casual rides.
