Great Alaskan outdoors dress code 101: No one uses umbrellas. Not for rain and most especially not for snow. What we do use instead is high-end outdoor gear with removable hoods. Specifically, the breathable kind with two way zippers, zip in/zip out liners and decent size pockets. Umbrellas are for Mary Poppins, not Alaskans.
