i'm presently looking into replacing my g/f's and my backpacks. for me i want something lighter since i've been trying to cut weight where ever i can, due to a bad knee. Presently i have a REI UL60, approx, 3lbs 2oz, it's actually fairly comfortable, and around the right size. the girlfriend is presently carrying an rei traverse pack.

this month i'll be buying some material and assembling an original model tarptent. so my space requirements for a tent will shrink and so will my need for that large of a pack. i'm thinking in the range of 3000 cubic inches, my girlfriend just needs a slightly larger pack, but i don't want to get her a heavyweight pack and she requires comfortable straps… i've looked into the jam2 for myself, what are some pack suggestions and opinions.
