I have a few of the L. L. Bean ones, and my kids carry them in their backpacks when camping to have a nice daypack to carry around instead of a full backpack. they don't pack down nearly as small as the Kiva or Sea to Summit, but are much more functional and durable. I have some Marmot and other varieties, they are nice, but do not pack nearly as small as the Kiva. If you are looking for pocket size EDC, the Kiva and Sea to Summit are the best I have found so far. OR makes one you can buy at Walmart for $5 or $6 that packs very small as well.
