Thanks for the suggestion. I was at REI last night and saw the REI Stoke 29 Pack and it only weights 1 lb 8 ozs and will carry up to 10 pounds comfortably. I am thinking of getting one of these for her and having her carry her clothes and toiletries and I would carry all of my stuff, cooking supplies, food for both and hammocks (and accessories) for both of us.
I think this may work as long as I don't get overweighted myself. I will let you know how it goes.
Thanks again for the advice.
