'Tried'... no. Fondled in stores? Some, yes. Most pouches are a full 6-sided heavy(er) fabric, and most have neoprene or padded shoulder straps, pockets, etc. I searched for something that would just:
1)take the weight off my neck
2) keep rain off bino eyepcs
3) require minimum 'handling' or movement to deploy binos
4) keep binos from flopping around even if I am crawling (literally)
5) involve minimum bulk so that I am unencumbered
I hunt in Eastern forests with a traditional bow and traditional methods (ground stalking). So for me, something even requiring a little latch, or which is made of noisy fabric, etc. is a non-starter. I wear a shoulder bag or fanny pack or daypack for storage etc., as needed.
I also - when not looking to fill our freezer for the year - enjoy viewing and observing wildlife, and birds in particular. Not suprisingly, I do that much like hunting, and the pouch is a great way to carry binos when out hiking or trekking about.
The harness is just flat webbing with some buckles (no bulk, less hot, fits under pack).
The fabric is a mesh like material towards chest - not as waterproof I guess, but the soft faced ripstop (waterproof) fabric towards exterior, forms a 'lid' which provides substantial cover. I have been in deluge, and it's of course not as good as a full-on pouch. The lid can be folded back so that I can pull the binos out one-handed.
The lack of bulk also means that if want to stow the whole thing, it's flattens into a pretty low-bulk package.
Anyway, not for everyone, but works for me!
Note that pics show binos with eyepc covers. I don't usually use them so that I can pull out one-handed ready-to-use (grabbed wife's 8x32 Trinnies for pic, which usually sits on kitchen counter). Also the top flap has an elastic cord so you can tighten it and then it'll snug up over top of binos. I don't, because i like the 'opening' to be wide so they come out and go back in w/out hanging up (again a result of stealth being important to me most of the time).
Looks like one of my straps going into pouch was twisted :-/
