Not that I'm pimping the pack that I haven't tested, but there are some gear photos of the kif t1 turned into day pack mode, and it looks smaller then my day pack. Maybe hirshey has some input on how her kuiu breaks down. It's your coin, but if you aren't using it for back pack hunting, then you don't need a pack that big, if you are, you don't need one that weighs that much.
I have the bikini and dt1 on order and plan on it coming with me in the field all the time, for all types of hunts.
