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.

An excellent helmet. Enough adjustment to wear with and without a cap and it has setlled in to the shape of my head and is now an excellent fit.

Great helmet,the flouro colour stands out in traffic making sure one is seen.
Great high vis helmet with the safety of MIPS. Great fit and high quality! Always love our Fox helmets.
Couldn’t get it posted so had to drive an hour to pick it up. Don’t worry understand why in this day and age postage is available on their online store or this and other products
Helmet is great and fits perfectly. The standout for me is the great customer service. The Guy was knowlegable, pulled out several helmets to try and find the best fit. Very Helpful and Friendly highly recommended
Fantastic helmet. So great you can adjust the size at the back. Well worth the money. My son loves it & willing wears it so that’s a HUGE bonus!

I bought this rad helmet, it was a Xmas present for me from someone, it’s too big, you won’t let me return it for credit or a medium, now I’m stuck with this rad helmet, which no one can wear. Very dissatisfied. What a waste of a rad helmet.
