Every day on the water has the potential for celebration. When the special moment happens, be prepared by filling Montana Fly Co.'s stainless-steel hip flask with your favorite libation. Anglers can choose from dozens of fishy patterns. Saltwater choices include various renderings of bonefish, permit, tarpon and more. The pouring (or drinking) spout of the 8-ounce flask is threaded for a screw-on lid fixed to a hinge on top of the vessel.
