Another Kifaru recommendation from me, I've got three of models now, the best packs I've ever used and the only people I buy packs from now. If you use packs a great deal and in demanding enviroments Kifaru are worth the money.
The waist belt size and back shape do vary depending on what you fill out on your order form, but there is also plenty of adjustment.
I had 5 packs but have had to choose one so kept the Kifaru and Ebayed the rest no contest. So what 3 do you have?
nice.I started with an OD Maurader, which I got from a friend, and was so impressed that I bought a CB Scout for jungle work. I've sold on the Maurader now and taken advantage of the low dollar to buy a OmniYoke + cargochair + a large Pod combination in CB for its versitality.
I get them sent to Brunei so as to avoid the Tax and pick them up when i'm there next.
