For such a well protected helmet, the O'Neal Orbiter does an amazing job at keeping your head cool.
There are 20 vents on within the helmet's shell, but more importantly, the main ones are all decently sized, so they suck in plenty of fresh cool air, backed up by internal channels.
The retention system has a nice big turn-wheel, which is easy to use even when wearing gloves. The fixed points are reasonably far forward in the helmet, so the adjustment does a good job of securing the helmet in place on the head.
As with a few other helmets that we've tried, the padded cradle felt unusual to start off with, but ended up feeling comfortable once we were used to it.
The visor is a little too prominent for our tastes though, and the magnetic strap closure attachment seems like a bit of a gimmick – it gets gritty easily, and as the usual clip does a perfectly good job anyway, why change it?
