Depending on what it weighs, and if you can get it to work, I'd be interested in working on a Mark II or Mark III version. My kids are slightly built (my 7 year old is almost 4 feet tall and 40lbs) and I am going to need a light pack for her to carry her personal gear, and let me carry another kid's gear...

I was thinking of hitting a surplus store, or an Army clothing and sales store at a larger base, to pick up their hip belt/straps for the Alice pack series.
