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.

Long peak gives better sun protection. Adjustable strap at back gives very positive fit. Unlike most helmets, this sits down on the head and looks half decent. The flûtons colour really stands out in traffic. Probably the best helmet I have owned. Usual excellent service at Bikes 99.

Fits really well with good adjustment for a growing head. Love the mips system and the extra protection it provides. Somewhat pricey, but a worthy investment to protect your little ones noggin.

Following the advice given by tredz when it comes to helmet sizing, I got a small as I'm in between sizes. Unfortunately this did not fit me, which I was gutted about because the helmet itself was solid, looked great and is a great price.I was more annoyed that I had to pay £3 to return it after following tredz own advice. I basically paid £3 to try something on. If you're in between sizes go up not down!
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.
I bought the mystery protection bundle and was very dissapointed you advertised it as a special offer and you get £200+worth of gear and when i added up the value it was about £120 worth of gear at a push. Not only was everything you sent all the cheapest items the shorts were badly made, no zip pockets or even a zip fly just an open hole at the front of them i don't know who designed them but I'm guessing not a cyclist. The Jersey was OK but you sent a short sleeve (again the cheapest option and probably a design you couldn't get rid of). The gloves I actually liked and the bottle as an accessory was acceptable but again a pretty cheap option. The helmet was ok but i was hoping for a full face, Basically I feel ripped off, and that you've just bundled together a ... MoreI bought the mystery protection bundle and was very dissapointed you advertised it as a special offer and you get £200+worth of gear and when i added up the value it was about £120 worth of gear at a push.

Also I tried using the first time buyers discount code and that wouldn't work either.
Forgot my helmet at home and didn't feel like driving all the way home. It was a purchase of need not want. Fit is good, light weight feeling. I am using this one solely instead of my original I left at home. Other helmet is a different brand.
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.
