proshell is thicker and more waterproof than softshell. The only reason I went with Goretex is because how light the shells are and you basically only need a baselayer under them to stay warm and dry.
Aside from the some of the silliness in this thread, it's actually been really informative. Thanks everybody.
One question though. On Burton's site, they list the AK 3L Hover Jacket as using two different GoreTex fabrics depending on the color. The "Acid and True Black" colorways are listed as using GoreTex Pro, and the "Schwag and Bluebird" colorways are listed as using GoreTex Soft Shell. Now, none of these 3L Hover jackets have liners or anything, so is there really going to be a noticeable difference between, say, the Hover Jacket in black or the Hover Jacket in blue?
