The Altieri Deluxe Model Oboe Bag is the Cadillac of case cover bags. The outer shell is a heavy duty water-resistant nylon packcloth that lasts for years. The interior is made of a special four-layer insulation lined with an ultrasuede finish that is lint and fuzz free. This model includes two outside pockets, one which hides backpack straps when not in use, and a shoulder strap. The other exterior pocket also has small open pockets stitched into the sides, some which stay closed with velcro, for tools and things. It will also fit any sized music, including orchestra folders. The interior will fit an oboe case and lots of other gadgets as well including the compact music stand found in the stands section. There is also an interior string that is designed to go between the bottom and lid, near the hinges, to hold the case in place within the bag.
