I have used this helmet a handful of times now and unfortunately the way the MIPS technology attaches to the helmet pulls my hair out every single time I use it. I have started to just use a bandana to reduce the damage- but wish I didn't have to in the heat.

Previous Giro Helmets fit well. This helmet made my wife ask if the helmet was a kids helmet. This helmet is so small, it seems like it was mislabeled from Giro.

Very light weight which also allows plenty of air to keep your head cool. After 5 minutes you will forget you have it on. Just for the record, Competitive CYCLIST is a great company to work with. Amazing customer service and shipping is as promised. I bought two helmets at different times and they both arrived in perfect condition and on time

I ride for a Giro sponsored team and this is what I use on the road and mtb as Giro's Aether and Vanquish (and numerous older Giro models) are too round for my head. This helmet fits more like Kask, Specialized, and Oakley. The quality actually seems a fair amount better than the Synthe! And the MIPS system is integrated better in my opinion than that in the Synthe.
AND, there is no problem with Oakley glasses hitting the retention device like there is with KASK helmets. And, yes, the Cinder holds those glasses VERY well in the front vents when necessary without obstructing your view and with ZERO movement (it can be tricky putting the glasses in if you're also wearing a hat as the hat material can slightly get in the way, so you just have to wiggle the glasses some).
A size medium fits me very well with just enough room for thermal cycling hats and regular cycling caps. My head measures 57cm and I wear a 7-1/8 in non-cycling hats. You don't always have to have the most expensive models to get what's best for you!

There isn’t a ton of interior padding, but the helmet is very comfortable nonetheless. The tightening dial in the back is a little small but gets the job done. Good helmet overall.

Got the hivs yellow and it is nice. Not the lightest nor heaviest helmet I have ever owned, but it does what it is supposed to and offers decent ventilation. Solid helmet!

Great option for keeping your dome safe on the road. Very nice fit system and great ventilation are offered with this helmet. Your head is snug as a bug with this and looks good too!

I have a lot of helmets, different brands, I really spect more. I can't say it is not good, but didn't impress me at all. It has a nice look, a fits good and it is not heavy. The Foray must be the same but shipper. The mips, holds your hair when you take it off. I should have chose the Synth. I didn't became my favorite, keep using other one.

This helmet was my 1st purchase with Competitive Cyclist. I was able to snag the helmet at a 50% savings. It shipped and delivered as promised.

Fit is great and provides enough room for a winter shell and sunglasses. This is a MIPS system and worth the step up in safety.

I highly recommend Competitive Cyclist. Great pricing on a consistent basis.

I really am pleased with this helmet. I have 3 different brands the straps on the Giro are the best. MIPS is very comfortable.

Wanted to try a MIPS helmet, also like that this doesn't have the long "duck tail"/aero back end to it like most helmets. Light, looks good and vents well. Fits true to size and price and service were great.

I've used the helmet numerous times. It is quite light, has good ventilation and very comfortable.

This helmet is surprisingly light and looks so sleek

Excellent construction, and good looks, if you are on the edge of a size if you can try the helmet somewhere before you buy it will be preferable
