helmet slides backwards
This helmet has one major flaw in my opinion. The way the straps are set up allows the helmet to slide back off of your head if you push it. It doesnt matter how tight the chin stap is, it still slides backwards. I tried adjusting it for an hour with no luck. I have a petzl helmet that fits fine and does not slide back at all. This could potentially be extremely dangerous, because when it slides back the chin strap cuts into your neck. If you took a hard enough hit it could potentially strangle you.
