Fly Racing Three.4 Helmet 5 5 2 2
Great helmet for price Bought this helmet for my gf. She a new rider and she loves the look and how comfortable the helmet is May 26, 2016
Really like this helmet. Comfortable helmet. Good air flow without being drafty on the interior. The lining is plush without being too soft. I like the graphics and feel that it's safe with DOT/ECE/SNELL ratings. I would buy this brand again. March 24, 2015
