Yeah, if you want to use it, the shoulder straps, hip belt etc are all on the frame, the bag attaches to it, totally modular setup, allows you to run different bags for different tasks
Yes, you have to buy the frame and bag separately. However, with just one frame you can have a daypack bag, an overnight bag, and a bag that fits your sofa, TV Satellite, and everything else for when you just have to get away.
Fat, I don’t own an older gen frame. But, it is my understanding that they are very ridged and will carry everything including the kitchen sink. I think that goes with being a Kifaru. The latest and greatest is just something he. Not sure they can get any better.
