This is a stylish helmet design by Fox that unquestionably will be highly protective. The visor extends very far forward, offering a lot of sun protection over the face unlike most visors. My one note of design improvement is that the foam could have been better integrated into the helmet. It's a different colour than the rest, and thus stands out. Given how bulky the foam is as a result of the MIPS, it would have been ideal to integrate the colours so they looked seamless. All in all, very happy with the quality of the helmet for the price.

Great helmet, adjustable fit worked well. Comfortable plenty of airflow. Love gut weight. Color matches both my bikes. Can't beat free shipping.

Fox’s great quality. Online best deal. I think size runs big. Wear a large in all other helmets so just ordered a large for me and my son, all the way is just barely snug. Need a medium. Definitely go by chart and measure

I bought this helmet as an upgrade from my old Specialized helmet before MIPS had become known. The helmet is exactly what I ordered and compared to list price, Backcountry had a great deal on the product I wanted. I have ridden with this helmet probably close to 150 miles now and have crashed plenty of times. :-( Fortunately no skull crushers but the helmet has kept me confident and safe. This model lacks good ventilation IMO but that seems to be how these companies get you. You gotta buy the most expensive model to get the better airflow. The harness tightens up easy and the fit is good. Once it is on and tight it stays in place and rides well.
Excellent product; fit and style are superb which you expect from a Fox product. MiPs technology which is good for added protection. Comes with multitude of colors.
I bought this to go with a new bike purchase and the helmet is very comfortable and generous in size and had a long brim to block the sun. My head is a 7.5 inch and large fit perfectly. The Smith helmet I was looking at was slightly smaller in the large size and had a smaller brim.
First it’s a nice helmet and I expect to use it for a long time. I ordered a large by mistake. It was too loose but around the ears and chin strap it fit well. I ordered a medium and I can get a great fit on the helmet but the chin strap is too snug even adjusted all the way out.Maybe I have a weirdly shaped head, but I think it’s pretty average. 😀 Great overall, but the strap needs better fit over ears and longer chin strap.
Nice mtb helmet. Very good protection. Would buy from again. tks.
Nice looking helmet but...it was already 15 months old when I received it from Fox. Fit is good. Easy to fit. Semi-comfortable after snugging it due to no padding on the back half. I lost 1 year and 3 months of its use due to Fox selling old stock as fresh. I change helmets every 5 years if there were no impacts to shorten their life. Over 20% of its life was gone when I received the helmet through Fox's online sales. I think I'll stick with Specialized helmets.
I have this helmet 4/5 because it fits but not as well as my Giro one. Also from owning previous FOX helmets these helmets fit bigger so measure your head before ordering. What I like is the price, it's MIPS and lots of ventilation.
