Great
I’m a truck driver, so I only use it when i get of the truck for couple of minutes on the job site. I feel it moving even I have it very tight. I don’t know what’s going to happen if i have to wear it constantly

Great helmet
Super comfortable helmet and crazy affordable for what you get. I wear this while doing home inspections in Arizona and the vents on the side are key! It's very comfortable, light and doesnt look like a mailman's helmet. Recommend this helmet for sure.
