  • full protection for commuting
Color: Matte Trim Red (Discontinued) Size: Large (59-63 cm)
I commute 2000 miles per year on city streets and decided it was time for a helmet that provided more coverage, and one that had MIPS. After all, what price do you put on your own brain bucket? I have had several Giro helmets and liked their designs. I chose this because it has extra protection around the temples, plus a lot more protection for the back of the head. It also has a harness that cinches securely to the head. (I looked at another brand that had a pony-tail cutout in back--an unacceptable compromise in coverage, for me anyway!) I wear L or XL hats normally. The regular size in this helmet fit okay, but didn't have quite enough spare room for a winter beanie. So I got the Large. It fits way down on my head, just above my eyebrows. It feels a little strange but doesn't interfere with vision. And the forehead padding is quite effective in stopping sweat in my eyes! It cinches down very securely: the shell can slip but the harness does not (MIPS). The rear ratchet knob is very easy to adjust. I like the longer visor to block the sun while commuting. I don't need the visor to flip up, as I never were sunglasses. But it still works fine to attach my Bike Peddler rear view mirror. Just make sure you keep the visor in place or the mirror will be out of position! ... show more

  • Good helmet
Color: Matte Warm Black (Discontinued) Size: Small (51-55 cm)
It's a good helmet, the straps are a little short but a really well built and reliable helmet.

  • great protection
Color: Matte Trim Blue (Discontinued) Size: Medium (55-59 cm)
I commute on city streets every day, so I wanted a helmet with maximum coverage (short of a downhill helmet). This one, which I think is actually considered a MTB helmet, covers the back of the head and the temples. And the MIPS harness allows the shell to move around, which seems odd, but that's the way it's intended, so the shell takes more of the impact. I have a fairly large head and normally buy XL or XXL hats. I ended up getting the Large size. It is quite large and sits just above my eyebrows. Some people won't like that, but I like that the harness feels thoroughly secure. It also prevents sweat from dripping in my eyes as much. I tried a Medium, which fit, but didn't expand quite large enough to accommodate a winter beanie. The rear compression knob is easy to turn, and the straps sit comfortably on the side of my head. Plus I really liked the glossy red color! To each his own! ... show more

  • Very comfortable, fit is as described, would like a better sweat management
Color: Matte Trim Red (Discontinued) Size: Medium (55-59 cm)
This is my third Giro helmet, previous ones were Giro fixture, this is by far more comfortable, better padded, fit is better, ventilation is better and it looks much better with the foam being covered by the plastic shell. However I would like a better sweat management do direct it away from the eyes, having driving it in the summer at 30+ Celsius and 80%+ humidity. ... show more

  • Good quality and very comfortable
Color: Matte Trim Red (Discontinued) Size: Small (51-55 cm)
Tried lots of helmets and this was by far the most comfortable. Got another one for my wife too.

  • Fits great! Easy to adjust fit! Stylish!
Color: Matte Trim Blue (Discontinued) Size: Large (59-63 cm)
I love this helmet! No complaints. Just put it on and crank a nob on the back until its snug, clip the chin strap together and you off riding. I liked the look of it the most before I new it was mips. Had to try it and cant believe how far helmets have evolved.

  • Great fit but watch the size charts
Color: Matte Trim Red (Discontinued) Size: Large (59-63 cm)
The size chart in the upper picture area is correct (Superfit size chart) The chart in the full description is NOT accurate. Here's a sizing hint: I wear L-XL Flexfit Caps. Measured my head at 23 3/4 inches. The size Large Giro is perfect, the adjustment right in the middle. Its a great helmet, with the most protection area. Actually sits around my head, rather than on top of it. ... show more
