The Trekking Double Trumpet Case from the house of Thomann is designed for two Bb trumpets with Périnet valves or a single cylinder valve trumpet. This case is constructed out of heavy-duty Rock-Tex material. This fabric is water-resistant and extremely robust. As a result, this case is ideal for travelling musicians given that Rock-Tex effectively protects your trumpets from external elements. The trumpet case features a large exterior pocket for additional storage and retractable backpack straps for carrying comfort. The padded handle provides good grip while the bag is being carried from one place to another.
