I have the Jumbo and use it as EDC. I like it alot and agree with Malpaso - if you're going to be doing some serious moving - might not be the best choice. For simply walking, though, it's fine. I like the Nalgene size pocket. I also added a compass/ first aid pouch to the rear strap mount. I keep finding more and more things to fill it with, though, so I may add more pouches with time.
