What Is a Rucksack and How It Differs from Other Bags

When I first heard the word rucksack, I wondered if it was just another name for a backpack. Over time, I learned that while they are similar, a rucksack usually means a sturdier, larger bag made for hiking, camping, or military use. In this essay, I’ll explain what a rucksack is, its main types, and how it compares to other bags.

Part 2. What is the difference between a rucksack and a backpack?
