This is a newer design by Altieri, the maker of fantastic case covers with backpack straps! The Altieri Oboe Laptop Backpack Gigbag might be the best of all possible combinations. It holds a laptop in a dedicated sleeve, and your oboe case in a dedicated sleeve, with some room on the interior left over for tools, an accessory tray, an oboe stand, perhaps even a purse. It is sized big enough that it can hold a professional music folder without being tight around the corners. All this is made in Altieri's special 4-layer quilted interior that helps control temperature fluctuations, preventing heat and moisture, and helping to protect against cracks and tuning problems. And there's still an accessory zippered pocket on the front for more of the things you need to carry.
This backpack/gigbag is taller than your average backpack, and it is capable of holding a double clarinet case, two single clarinet cases, possibly up to two oboe cases, flute, or piccolo, or a combination if you have doubling requirements. A larger size is available by special order if you need the backpack to hold an English horn case or a double (English horn plus oboe) case.
The backpack design has a carrying handle on the top, a shoulder strap, and backpack straps that can be hidden in zippered pocket if not in use.
