Sleek style and great quality!
I had to get a new helmet after falling in my old one and hitting my head pretty hard. I know a bunch of my riding friends have this brand of helmet so I decided to try it out and I love it more than my old one! It fits really well and looks so nice when I'm wearing it!
Perfect for Round Heads
I'm on my second One K, and I love this helmet! I have a round shaped head, and helmet like the Charles Owen often give me headaches on the sides of my head. This helmet fits exceptionally well, and the moment I first put it on it felt secure and like it would provide great protection in a fall. It's light enough with great ventilation for the Texas summers, and I really like that the liners are removable so you can wash them. Turns out I'm on my second one because I did fall off my 4 year old. It was a shame throwing out the first one because it still looked beautiful, but I'm thankful to have had such a well designed helmet on my head!
LOVE this helmet!
I've had this helmet for about a year and a half and I originally bought it because my CO GR8 didn't have any ventilation for summer riding. Out of all the helmets I tried, this one fit the best and had amazing ventilation. I can actually feel breeze when I ride in this helmet and it doesn't leave my hair all sweaty after I'm done! Definitely recommend this helmet!
