A backpack is one of the most versatile pieces of luggage out there, it’s associated with adventure, freedom and travel. It probably dates back to our primitive ancestors but its true origin is unclear. It is also one of the most important inventions in human history for its function. It allows you to carry heavy loads on your shoulders leaving your hands free to spear a fish, climb a tree or swipe your credit card.
Most backpacks are closed with a buckle mechanism or a zipper but some use a drawstring fitted with a cord lock for the main compartment. They are often padded for comfort and have a strap across the back to increase support. They may have a removable waist belt and sternum strap for extra support and to decrease the weight on your shoulders. Most backpacks are made from a waterproof material to protect your belongings from the rain.
Many backpacks are designed to be carry on luggage, avoiding the hassle of checking it in and waiting at the baggage carousel after your flight. It is important to choose a bag that fits the airline’s size restrictions as you don’t want the airline to force you to check it.
Most backpacks have internal pockets that can be zipped shut which can be useful for storing valuables like a wallet and passport to prevent theft. Many also have a hydration sleeve that can be accessed from the back panel or interior pocket for easy access to water.
