I bought this REI-branded pack, on sale, at REI in 1982. It was probably made for REI by Kelty, and seems modeled after the Kelty Tioga of the day. External frame packs are largely obsolescent now, but I find I still prefer them. I bought a large internal frame Gregory this year, and have been pretty disappointed with it. I am thinking of selling it and trying a big Osprey pack, and if that one doesn't please me any more than the Gregory, I'll get rid of it as well and stick with this old external frame. There's nothing wrong with it, though it would benefit from a bigger, more comfortable hip belt.
For the most part, I have been packing it the same way since I first acquired it. I am a creature of habit and my pack loading habits make stuff easy to find.
