Easy forgot that you are using it.
With its weight of 1,590 grams and a remarkably wide angle of view, this helmet is both very comfortable and affordable.
I tested it on a long trip, wearing it continuously for 5 days, and I have no regrets.

Helmet saved my life.
Guys and ladies, there is only one thing to say. It's safe!
Through the grace of God let me wear a O'Neal Sierra helmet, it saved my life. After a motor cycle accident I was unconscious after hitting my head on the ground. CTC scans done by doctor indicate no skull cracks nor concussion. Next order will be another O'Neal Helmet. 5/5 rating

A visor, shield, sun shield and adjustable ventilation are good requirements a helmet should have when you ride an EUC. This helmet has it all and I am happy with my purchase several months of usage during cold season. It may be too hot for summer but that remains to be seen.

Nice snug fit, good value for the money/comfortable. Chin cover keeps falling out though, that's the only problem with it. 4 stars instead of 5.
