Bughalli, if you go to the Kifaru website and look at the hunting frames they have a picture of three packs lined up showing a side profile. You can clearly see a straight black Frame in the middle and the two end packs are curved at different levels of curvature. I tried to copy and paste but I do not know how to do it on the phone. Maybe someone can do it for me. The sales person at Kifaru sounds like he is not informed. The would go back and get a more knowledgeable person to help me.
Nevertheless, you are definitely doing the right thing by try before you buy. When I was younger I could use almost any pack and get by but now that I'm older I'm looking for more comfort. Wish I had done that 15 years ago. Goodluck. Fatrascal.
I was very surprised when the Kifaru rep said it can't be shaped to my back and only the old model did that....because I thought I read it on the site as well, but I figured he would know since he works there. Now I question if he knew what hip belt I had on because I expected it to be amazing and it was just average. Unfortunately I have no plans to be back in Denver any time soon.
