I have a set of Wiggy's ultralite waders that work great for backpack hunts that involve mulitple stream crossings or getting in and out of float planes/boats. They are not the most durable waders I've ever had, but for weight and packability they do the trick.

I also own an Ultima Thule (-20) bag. For being a -20 synthetic sack, 5lbs is not outragous for weight, but as WoodsWalker said, the thing compresses like an angry bear(or at least to the size of angry bear)! Overall the bag is warm as hell and seems to do as advertised.
