Lots of great packs on the market so it makes it harder to decide. After looking at several packs, I recently bought the KUIU Icon Pro 1850 for a day pack. I bought the 6000 ultra bag so for backpack hunts, I'll pack in with the 6000, then put the frame on the 1850 and leave my gear in the 6000 at camp. I really didn't like the idea as promoted by a couple other packs to use a 3-5000 size bag for a daypack and a big backpack as I'd be needing to switch gear around more than I wanted to. Considering price and weight, I could get the 2 KUIU packs very similar to others. I did look at a few others but this system seemed to fit what I was looking for the best. Hasn't arrived yet so I was going a bit on a buddy's opinion that has these packs and he loved it. I'll be cutting off a lot of weight from my Cabelas Alaskan bag and Badlands daypack that I currently use.
