This is an amazing piece. It is meant for carrying water back to camp, but I like to use it as a daypack. It worked great for going to get water in Montana on a backpacking trip. Then it served as my day pack the next morning. I carried enough stuff for my girlfriend and I for about 5 miles up to the next lake that was on our trail. That included two packable rain jackets, two small ziploc bags full of snacks, a water filter, a water bottle, a sitka ascent shirt, and a zoom lense for a camera. I probably wouldn't take much more than that in it, but it worked fine. It packs down small enough to fit in a large cargo pocket or anywhere in your big backpack. I also use it to retrieve trail cameras and other small tasks around home like fishing. For anyone who doesn't need to pack a lot, this pack is for you. I took away half a star only because in warm weather, it makes your back sweat extremely bad since it's not breathable. But that's a minor issue that probably won't happen this fall. In archery season, I'll carry a rain jacket, core heavyweight hoodie, a few snacks, a water bottle, and possibly a down jacket and camera.
