Backpacks are defined as the modern American Every Day Carry bag. They adorn the shoulders of school kids, college students and members of our military. Red Oxx Rucksacks are a historical descendent of the famous flying airborne rucksack (also called a knapsack). Perhaps the most common backpack is the book backpack. Our K-12 Kat Pack Backpack is an ideal book bag, due to it's rectangluar shape and clam shell opening design. It also features a laptop sleeve, ballistic bottom, a larger raised front pocket and is guaranteed for life. This is the backpack for boys that typically destroy one in a season. Since the Kat Pack has a lifetime warranty, it's not likely to get returned for repair. The best work backpack for men is the C-Ruck Carry-on Rucksack. Stepping down in size, there's the Roadster Mini Ruck Rucksack, sized for smaller frames, or women and children. All three of our packs make great school bags for adults, too. Why fill a landfill yearly or even seasonally, when you can treat your kids, or yourself, to a backpack or rucksack to last a lifetime?
