Needing a bigger pack for 5×7, I settled on a modified Kelty P1 from Photobackpacker.com. A nice upgrade from my Kelty Redwing- better suspension, more room, and still lightweight. But the full zipper allowing total access to the main compartment was the main attraction. The zipper on the Redwing stopped about 6″ from the bottom of the pack, making access to the stuff at the bottom a hassle.
