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.

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.
