I was wondering about the comfort of a GoLite Jam 70 (using it within the suggested weight limits, of course)... Unfortunately, I do not fit most standard-sized packs very well, and it is not adjustable. Would the single aluminum stay be enough to comfortably handle a BearVault 500, sleeping bag, clothes, pad, etc.?
For those of you who use the 70L Jam -- is the waist belt adequately padded? Do you have to pack so that your sleeping pad provides extra cushioning along the back panel? Is there anything else I should know about the pack's comfort?
