The Mamba is pretty good. I like the fact that its quiet enough to hear my audible. I've had problems with my Protec and Nvertigo. If you want a quiet ride this is a good helmet. It goes on super quick in the aircraft so I don't have to worry about getting it on until the plane levels out. It only takes a couple seconds. What I don't like about it. It doesn't fit very well. Sometimes it seems tight, sometimes it feels good, last time air was rushing in on the left side of my jaw. The visor doesn't quite marry up with the unit all that well. It makes me think the pin and hole retaining system will fail someday as 3/4's of the pin doesn't get into the hole. There should be some type of tightening system that runs through the back of the helmet. All that retains the helmet on your head is ergonomics and a chin strap. I particularly dislike the internal audible pockets. I don't understand why the designer thought putting an expensive audible right next to the only nuts and bolts on the helmet is beyond me. I solved the problem by building a little pad of electric tape and cardboard against the nut but it almost makes the audible not fit. The only other thing I don't like about this helmet is that you cant talk to anyone else once you've put it on regardless of having the visor up. Its annoying when someone says something at the last minute or you can't alert someone on the dropzone that you're coming in on final near them. The helmet is very secure. I've made about 15 sitfly skydives in the helmet without issue.
