Replacement Rexine Bag for the Full Size Bagpipes. The bag is approximately 25 inches long x 10.75 inches wide. Rexine is a soft, synthetic, material designed to be air tight and to feel like high quality suede. The Rexine bag features a contoured goose neck for better airflow. Unlike the natural leather bag, the Rexine bag requires no breaking in period, and no seasoning. We think all pipers will appreciate the design, the texture and the lighter weight of this set with its Rexine bag.
