I bought this helmet because it was inexpensive and because of the awesome goggle channel. The goggle channel seemed like a great idea ; take the goggles down just before you get out of the plane without taking the helmet of.
But you can't remove the strap on most goggles, and the goggle channel can't be opened, so I had to make my own custom goggle strap to fit my goggles.
But it turned out to be a waste of time. The goggles are way to loose in the sides because the goggle channel is routed on the outside of the liner. If I tighten the goggles more than this, it's really uncomfortable and I can't put the goggles up on the 'forehead' of the helmet any more.
The goggle channel is a great idea, but it just doesn't work.
The helmet itself is just fine. Fits nicely and provides good protection. The surface gets scratched pretty easily though.
