I just received mine and will be returning. The design is a good start, but needs improvement.
Pros: Layout of pockets is good. Like the hydration pocket.
Cons: 1) One-size fit all is bad idea. I'm 5'10" and 160 lbs. I had to cinch the straps all the way down and it was still a little loose. BUT when you do this you can NO longer use the water bottle pockets. 2) The seat magnets are pretty strong, but when I did the jump test, the seat would release and fall every time. I don't the seat falling when I brush tree limbs and such. 3) Heavy. Even when I removed the frame it was still heavier than the Tatr II and III. With the frame its really heavy. 4) The frame itself is curved/contoured and felt okay standing up. But when I sat down it makes the vest ride way up.
The Cabelas Tatr's are better IMO. Now to decide on tatr II or III..
