I picked up a "Magic Washcloth" from Old Navy the other day. Its basically a super compressed 10 inch by 10 inch washcloth.

I thought it would be a flimsy POS usable once or twice. Quite the contrary is true. It is a standard build, reusable, machine washable cloth. It is unique do to packaging. They have it compressed down to about 1.5 x 1.5 x 0.25 inches. One caveat... it only expands when thoroughly wet.

I picked up a couple of extra to throw in my large kit and my travel bags. Not exactly something that one would desire for an EDC but might make a nice, light, compact edition to a BOB or 1st aid kit.

BCB sell a sponge that sounbds very similar and would be ideal for when gaining water was a problem-the one on BCB's site is tiny!!! and EXPANDS to a rather latge size!!!!
