I don't have much info for you but just yesterday I received there XKG Windstorm rain jacket in Mountain Shadow. It's supposed to be 3xl but I would say its a large 2xl, jacket is slightly larger then Cabelas Space Rain jacket in 2xl Regular. Comparing the XKG to the Space Rain for fit and finish I would say that the Space Rain is every bit as good plus half the price. I will be keeping the XKG just because it kind of fits me better then the Space Rain but if Cabelas happens to come out with there jacket in 3xl any time soon the XKG will be going back to Amazon. At this time I have no idea if either jacket is waterproof.
Weights
XKG Windstorm jacket 3xl = 16 .oz
Space Rain jacket 2xl Reg. = 12.4 .oz without stuff sack.
Space Rain pants 2xl Reg. = 9.1 .oz without stuff sack.
Space Rain stuff sack = .6 .oz
