WATERFLY Small Lightweight Packable Backpack: 20l Ultra Light Foldable Travel Hiking Camping Daypack Day Pack for Man Woman

Great for budget backpacking! I used this as my day pack and it was great! Straps are a little thin and unsupportive, but the backpack itself is great quality. Lots of pockets (even some hidden ones). I was able to fit a wetsuit, waterbottle, lunch, and other things in it.

Seriously, this little bag has no business being this good. It doesn't pack up as small as some stuff sack styles but is as capable as a decent dedicated backpack. Perfect for a couple of six packs and some snacks, a days worth of supplies or some light shopping. Two full size water bottle pockets and heaps of solid zipper pockets. For the price, just get it!

Perfect. I like compact, light, and self storing. Size is perfect, as I have a larger BOB. This one is for around town, and stowes away nicely anywhere.

Super useful and can be used pretty much anywhere and for anything. Very comfortable and can take a surprising amount of material. Really easy to use and pack away - love the way it can be folded into a small carry bag.

Loved it. Used it on a short trip. When I was done it zipped right back in a small pack.
