Anybody have a pair? If so, thoughts? I’ve got a pair of Drake, Frogtogs (amazing for the money!) and old school Columbia’s. I’m wondering how the Sitkas holdup. Does the zipper stay watertight? Do the boot seems stay together? How warm are they? Basically, are the damned things really worth $1000? Because I know a half dozen fellas that swear once my Columbia’s go the way of the do-do I need to get Cabela Supermags.
