Love this helmet. Super comfy, quiet in the wind, pretty warm when it's cold out (with my bubble shield), and looks great with my bike. Pretty low profile for DOT, and awesome quality. I wear it with cheap ray ban knock-offs during the day and am super comfortable! I tried on a lot of helmets before deciding, and this was by far the best. If you want an open face helmet, don't even hesitate to buy this. You won't be disappointed.

Bought the Rootbeer bonanza helmet and took it on a 1000km trip. Absolutely stable. No lift. A bit of wind noise as expected, but a set of earplugs will fix that - and that only became an issue after 300km and I have tinnitus which doesn't help. I used the biltwell goggles for eye protection and can recommend them too. Over all. Love it more every day. Definitely grows on you.

The product is better than expected. It not only looks awesome but its really comfortable. Erik and the team at Biltwell helped me out with some shipping and sizing issues and made sure I got the right helmet.

Thanks Erik and the rest of the Biltwell Team!

This helmet fit perfect and was the best replacement for my old Hustler. Always have had a great experience with Biltwell products

The DOT-approved Bonanza version looks a little bit bigger than the novelty version. However, when I tried both of them Bonanza is much more comfortable like it says. Also it gives more safety. I love it.
