I've used white buffalo packs for years. They are the most "practical" pack I have owned. Allow me to elaborate: my badlands 2200 is a great, ergonomic, pack, but it fails in the practical application department. The top pocket on the badlands sacrifices roominess for the "smooth" look, so the loaded pack looks nice, but I cannot use the top pocket if the main compartment is filled with gear. The white buffalo, on the other hand, is just a common sense design, where if I fill the main compartments, the smaller pockets are unaffected. Also, in order to use my badlands hydration system, I have to go buy a square bladder. The white buffalo uses the conventional rectangular bladders, and comes equipped with one.
I generally end up using my badlands for scouting, and the White Buffalo when it's time to get serious.
As a side note, I, and others, have used White Buffalo packs as our primary bags for Search and Rescue work. Again, the pack is just an all around practical pack.
Definately a good buy.
