Excellent lid. Very well made and great coverage. Replaced a POC ventral spin and the quality of these are outstanding!

Overall a pretty good and safe-feeling helmet. I like how it fits further down on my head than other road style helmet. The ventilation is pretty good, could be better. If I stay standing still long enough mid-ride, sweat will escape the padding and drip into my eyes (I'm a particularly sweaty individual).As far as fit goes, I have a larger head (~61cm) so I ordered the largest size and he just barely fits with the adjustment rolled out all the way.I'll also say it does fit my ponytail real nice!

I bought this helmet 3 weeks ago, got accident recently. Lucky enough no injuries. Sustained the impact for head injuries. Excellent product.

Liked it so much this was the second one purchased (also because 99 Bikes had a good special on it). Works really well for a plait or high pony tail as the helmet has space inside the helmet for the tight part of the ponytail. Means the helmet actually fits rather than bobbles around like other every other helmet brand (expect possibly one Scott helmet but couldn't find it to try). The hair can go up through the rear of the helmet for good fun factor, or down the back like other helmets. Also the pretend MIPS system doesn't catch on hair making the helmet more comfortable as well. Looked at over 50 helmets and this one the only one with room to work with a high ponytail plait without compromising the rest of the fit. Finally a helmet that fits well (so bought two).
Helmet looked really good but did not fit as well I was hoping for. although it was a great value at the sale price I had to return the helmet back to the store.
All around great helmet at a great price.Excellent look, fit and ventilation. Very light. I definitely recommend it!
So far so good, I have done about 30 miles wearing it. Nice ventilation, it fits perfectly. I was afraid of the size bc they come in combined size; I ordered an L/XL. I have to say that it is not as big as other companies that have this type of sizing, so I’m very happy about that too.
Bulky and big feeling for an intended road style helmet. Construction and materials did seem killer though.
I'm right up on the size limit, My S/M took adjustment to get fitting good. The rear ratcheting adjuster needs to be pulled out from the inside of the helmet and placed into it's lower slot. This isn't in the manual and at first doesn't feel as if it's not meant to be removed, leaving me worried I was going to break the helmet. Thankfully it's just a well machined pop in/out style adjuster and once it was out; adjustment was made much easier. While my Giro helmet of the same size specifications goes on/off much easier, with this helmet I have to set to the max size to put on, then tighten to fit snug else the adjusting plastic around the ratchet can get stuck under the helmet causing it to dig into the back of my head. Size up if you can. Well made lid that is a ... MoreI'm right up on the size limit, My S/M took adjustment to get fitting good.

I bought the helmet a couple months ago and I’m very satisfied it fits great has great air flow and looks pretty decent especially for the price
