Thanks everyone for your input.
oldsoldier: The two sides did come separated the same way yours did.
falcon5000: Those look like good bags. My EDC is for traveling on the subway to my job (not a BOB), so I wouldn't be carrying something like that. But I passed the site onto an officemate of mine who does a lot of camping and some water adventures. She thanks you...she'll be showing her hubby!
Some people swore by these bags so I thought I'd try. If they fail on me it's not a catastrophe, but for anyone in the wilderness/water, it could be a major problem. I would never trust them.
It's like the s-biners I bought--once I got them I realized how fragile they are. And McGizmo clips and the like have failed in my pocket--my LM Squirt always disconnected. I guess you have to try for yourself to determine the faith you'll have in them. As an aside, the one clip that has held in my pocket is the one that comes with Doug's Photon Freedom light. I don't think the "spring' is any tighter than other clips I have, but it is round. Maybe it's a "center of gravity" problem with the other clips--too narrow, no where for the items to go.
