This Manhattan Portage Coin Purse has been handy for trips to the park, our daughters' field trips, as well as other excursions where I've wanted to have some money with me, but didn't want to carry my purse. The fabric is heavy duty, as well as the zipper.
It is slightly smaller than I expected, but that hasn't been a problem for what we've used it for (carrying money, ID, change...) The clip attached to it is also heavy duty, and probably one of the things I like the best about it. It has been very easy for our youngest daughter to clip this (with money inside) securely to a belt loop during field trips, and the zipper has never come accidentally open, nor has it come unclipped.
I would recommend this to anyone who needs something small (it is slightly smaller than I expected) yet sturdy for the purposes that I've described above.
