These packs are Idaho made by a group of local hunters that I really respect. The frame and bag follows very similar concepts to that of Mystery Ranch and Stone Glacier. They have a video on their website with information about their frame. I like the concept and being that I have a Mystery Ranch and a Stone Glacier I'm excited to give this one a try this winter/spring.
