Amazing fit, MIPS safery
I bought this to replace a Giro montaro thinking it would be a lesser product but was impressed by its comfort and ease of fit.

I use this helmet for trail riding and like the how the fit keeps it from moving around when going over the rough stuff.

Great mountain bike and all around helmet
by Down hill don

My girlfriend and I are casual weekend bikers. After getting into mountain biking it was time to start wearing a helmet. After a bit of searching I was sold on the 4forty. It arrived fast and i was out trying it out on the trails the same day. It had a good solid fit and plenty of ventilation. Two weeks ago (out of the blue) my girlfriend asked if she could borrow the new helmet (since she does not own one) to go for a ride with some friends. Afterwards she mentioned how easy it was to adjust, how light it was and that it was well ventilated. She has since even began shopping for a helmet for casual rides. This helmet is highly recommended

Looks cool, feels cool, and provides excellent protection for any kind of cycling IMO

I'm a cycling tourist and tend to outfit more towards MTB than road. I wanted a helmet with excellent protection for asphalt riding our long distance touring. The MIPS technology was impressive. Also appreciate the Sweat Guide that prevents forehead droplets from getting into my eyeglasses. Great product, killer colors and look.

This is a solid helmet that has worked well in the AZ summers for MTBing. I wanted something with MIPS, and was happy to have it fit well and be much cooler than the older helmet it replaced. I'd buy again in a heartbeat. Highly recommended
