Very versatile case, can carry just about any pair of glasses, as well as a broken down M Frame with 3 lenses. A bit bulky on the outside however.

I have the US Standard Issue case. It works great. I'm glad it was the clip. I can clip it to my belt of store it in my bag. It's a little bigger than I thought bout it's got tone of room

This one is great...
It is not to big considering the amount of hardware you put in it.
The extra volume give me a safe feeling when I'm on the move.

For a smaller case or vault for one pair you should look further..

I love this case, plenty of storage for your lenses, although heaters can be a bit of a tight fit. I wish it could hold more lenses, but then again i wouldnt really want the case to be any bigger than it is.

These are great if you swap out lens often and are on the go.

I use mine on campus with to hold a clear lens to use as safty glasses

the best part is this case isn't huge compaired to square cases of a previous generation
