I have several large bags, but do not carry any of them around.  This is perfect, it folds into itself and waits in your purse, and is ready anytime you need a large bag.  The zipper works well, folded it is a little larger and rounder than a pack of cigarettes.

I visited a sick friend and volunteered to do some laundry.  I stuffed a whole washer load into this bag, took it home, threw the bag in the washer with the laundry, folded and put it all back into the clean bag!  The bag does not fade.

I have had it less than 3 months and have used it about 4 times; when folded into it's pocket I see some tension on the seam stitching. Will update the rating if it pulls loose.

I would definitely recommend this to a friend, may consider it for gifts, and buy another one to keep in my car.
