Yup, those 13.4s are nice gear. The issue w/ the ANR stuff is that it gets fried at the boat, even on non-SPY ships. One issue I see w/ those Alphas is the visor hinge point. Obviously I don't have it in my hands to look at, but in the pic, it looks like it could crack or snap when it's not being used (like something banging into it). It may be better designed than that in real life. A better balanced helmet for NVGs would be a welcome thing for my long head. I'm right in between sizes w/ the Gentexeses.
Interesting info on the helmets, Chuck. I wondered why the CG didn't have white, especially when they're in the life saving business. My only concern would be what if you aren't aided when you're looking for that guy. It does happen, like at dusk.
