### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great helmet for Onewheeling!
  

*by C***N on Reviewed in the United States on March 29, 2021*

I know this helmet is for downhill mountain biking, but I got it for riding my Onewheel and it works just as well for that. My head circumference is around 55cm so I got the small going by the size chart. It fits really well, but WITHOUT the cheek pads. I immediately had to take those out. I know they’re SUPPOSED to fit snug, but the pads were squeezing my jaw uncomfortably tight. Without them the rest of the helmet is just a liiiiittle loose, but I did take a spill and the helmet was no where near loose enough to fall off so that’s good.It’s very comfortable, fairly lightweight and seems quite breathable. I’ll see how that stacks up in warmer weather once it starts to get above 60F. But so far so good.Also, the helmet looks GOOD. Most helmets make me look like a bobblehead ‘cuz I have a small head, but this one doesn’t look so bad on me.Has more peripheral visibility than a motocross helmet as well.

    Quality, good fit
  

*by J***Y on Reviewed in the United States on November 7, 2023*

I ride DH and needed a quick replacement this helmet did the trick. I take a medium but took the advice a d went with the large. Perfect fit, snug not tight. Quality  is the same as my TLD and better then my Fox.

    Great little helmet.
  

*by T***R on Reviewed in the United States on October 30, 2023*

Use this for E scooter. 72v 4000w so on the faster side so full face is really a must. But most time is spent at lower speeds cruising and lighter weight and airflow is a requirement. This works well. Helmets are only good if you actually wear them and I find myself wearing it when others opt out of their motorcycle helmets do to their discomfort form heat and wieght. Plus the strap buckle is awesome! So easy to put in and take off. Sunglasses easily fit while wearing. The visor does grab the wind at higher speeds a bit.
