They redesigned the Serac so it can be run on it's own (or attached to any of their frames)- has detachable shoulder straps and belt (you can run the bag with the shoulder straps and sans belt if you want). It also has an internal frame (that can also be removed), not intended for load hauling, but could help out with heavier day loads (optics/tripods/etc).
I haven't seen any feedback on it yet, but I have one on order so will post some pics and thoughts up when I get it.
