I have 5 gallon mylar bags in my BOB's, but I wouldn't think of EDCing one of them. The ziplocks will have to do for that.

I like your EDC, it's well-orgainized. If I were going to add anything, it would be in the way of first-aid and possibly some other medical. I would add some gauze and tape. For my EDC, i took cloth first aid taid and cut the roll in half. I rarely go anywhere without some gauze pads. I know the tampon can really soak up anything including blood, and the handkerchief would be of use dressing a cut or something. So some tape would be the first thing I'd want to add, not sure I see room. You might crush the tube and heat shrink it, like you did for the tinder.

Welcome to the forum, please stick around.
