Protec's Flugel PRO PAC case features a strong and lightweight, shock-absorbing wood frame, thickly padded interior with soft velvoa lining, double mouthpiece section, large gusseted storage pocket, and is backpackable utilizing an optional backpack strap (Protec model# BPSTRAP, sold separately). The 1680 ballistic nylon exterior has reinforced zig-zag stitching that makes it weather resistant. For traveling, you have the choice of a dual-corded handle design with padded handle wrap, a thickly padded shoulder strap with grip surface, or a subway rope handle, to suit your preference. It also comes with durable molded rubber feet to make it safely stand when not in use. While there are long-lasting custom-molded zippers, the Flugel PRO PAC has a QuickLock which securely shuts the case with the need to use zippers. The built-in organizer includes two sleeves for pens, keys, and smaller accessories.
