Great helmet - purchased the adult size small for my 8 year son because he has a massive noggin and kid sizes were too tight. It fits him great and he feels like a cool mountain biker. Win win.

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

Solid helmet for the price point. The fit is adjustable and my fat head could probably fit into a medium but I went with a large to be safe.

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.
The helmet looks nice and fits well. I like it because it comes with extra liner pads for when the originals are worn and dirty. Comfortable and lightweight.
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.
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.
yes i followed sizing info but rins to big so i have given it away. seems nice otherwise.generally 0 fox given but in this case one fox given.
