  • Cool helmet!
I've had this for some time now. I wear it any time I ride. I like the design, I like the matte color with the bright light blue. Luckily I haven't had to "really" use it in a crash. But it is a snug fit on my head and can't complain about safety.

  • Seems like a good, low cost helmet
Fit my grandsons head, so far we haven't needed to test it against a fall from his quad :-)

  • Protects Junior's Noggin' with comfort
Junior loves this helmet. He is 4, and I ordered large youth. It fits him perfect, thus this brand runs Very small! Well crafted and padded.

  • Great fit
I was super excited for when this helmet came in bc we were leaving the next day for a 4 day family vacation to go four wheeling. The helmet fits a little loosely- I feel if I had gotten a medium it would have been too snug, so a large was just perfect. The cushioning is the most amazing thing and is super comfortable. Also the straps at the bottom have cushioning on them as well! My family are big O'Neil helmet fans, and I have them converted and purchasing these also bc of how lightweight and not bulky they are. ... show more
