> There are a number of bag that pack down to self enclosed things smaller than a phone.

Are the bags of a reasonable size when expanded? Can you please link me? I've never found anything both big enough to be useful and small enough to keep in my pants pocket at all times.

Ijust linked above. I never used these specifically, but similar. Plenty big enough (definitely better for carrying things than disposable plastic bags)

Those are too bulky unfortunately. If I walked around with one of those in my pants pocket, it would look like... well, you know what.

These are the type I use:

They fold flat and wouldn't cause much bother in a pocket but I personally don't like anything at all in my pockets. I keep them in my satchel and they are unnoticeable in one of those flat pouch sections that are pretty useless for anything even as slim as a wallet or phone.

They won't last forever but good for a few years so far. They have survived when I have stocked up on canned goods.
