Why are you concerned about concealing mouse guns in Alaska? Notwithstanding 2cooltoolz comment about concealing AR-15s in winter gear, in Alaska you can carry a Desert Eagle in .50AE on a headband if you wanted to.
But our "Summers" up here are brutal! Have to change out the Desert Eagle headband for the 1911 baseball hat! (Remember, if it doesn't get dark for months, you don't have to take off your baseball hat!)
