This is the Austrian military Alpine backpack, also known as the KAZ03 Bundesheer Rucksack. It boasts a whopping 65-liter capacity and includes all of the straps and compartments that you could need. The pack comes in the original and classic military olive drab color and is covered with various belts and straps to attach all of your gear. This makes for a great backpacking pack or bug-out-bag. Like all modern backpacking bags, direct access to the bottom of the pack is granted via a large zippered opening. These come in good used condition.
