Well it's made with Event fabric, so it doesn't overheat. As far as I can tell it looks like it's made similar to the NCD Jacket but with a nice hood. The only downside I could see was that it looks like it cuts off at the waist (which I don't like personally).
Aswell...
Just got the NVG mount today...tossed it on. Had to bend the bracket a bit to form better on the helmet.
