The Sax Pack is lightweight specifically cut to fit most E flat alto saxophones. The lightweight material is durable and water resistant. The Sax Pack comes with a generous pocket and high grade 550 parachute cord for easy carry. The Sax Pack is a great compliment to the standard hard case. When not in use the Marching Band Student can roll the pack up and stow it in a pocket. When the performance is over, the student can unroll it from the pocket and place the instrument in for added protection. Great for game day or for those long practices. Colors are black, navy, green, red and pink. Instrument not included.
