This is an extraordinarily comfortable day pack that can hold more than expected. Compression straps are very long, providing external storage Hip belt pockets on each side for phone, camera, Clif bar, etc Well-designed, pockets easy to access even at full capacity Included rain cover (Bonus!) There's also like a million loops running down the outside of the main compartment for strapping light stuff that you don't want to swing all around and bother you. While you could, with some creativity, strap larger items to these loops, would not recommend it as you would want weight closer to your back/ hips. Having the pack at full capacity would certainly push these larger items way out away from your center mass. There is plenty of space inside the main compartment and my favorite part about it is the large mesh pocket at the inside top flips down when you unzip the main compartment about a quarter of the way. This keeps the stuff at the bottom from having to be exposed / unpacked when you want to access your map or other small items from inside the backpack. It can be accessed so quickly and easily and I love this feature. There is also and adequate side pocket that holds quite a lot, seems very sturdy, and is also quickly accessible.
