Weighing in at only 9 ounces the compact size makes it extremely easy to pack in the mountains. The all aluminum tube creates high screaming bugles with crisp clear notes and creates more volume than most full size bugle tubes. The Little Big Mouth utilizes the V.E.T.T. system mouthpiece for a 1 1/2 mouth opening and a narrow throat requires less air and creates optimal back pressure. The tube is covered by a water-resistant padded cover to eliminate unwanted sound while walking and to keep your hands off of cold aluminum on those crisp fall mornings and evenings. For use with your favorite mouth diaphragm call.
