The backpack is a type of bag used to carry light to moderately heavy items, worn across the back and over the shoulder opposite the bag. There are various types of bags, including the messenger bag, briefcase, tote bag, and book bag, each with different features and closures. Children using backpacks and book bags may be at risk of spinal and back problems, leading to the popularity of rolling backpacks.
Backpack refers to any type of bag used to transport light to moderately heavy items. A backpack often has a single strap that is worn across the back and over the shoulder opposite the bag. These types of bags have been used for centuries. Today, you can find the wallet used as a backpack, as a messenger bag, or to carry many other things. You could see most laptop cases as handbags, and most briefcases, especially those with a shoulder strap, as variants of the bag.
Unlike the briefcase or laptop carrier, the briefcase may simply be made of cotton canvas and does not necessarily feature a zippered closure. Sometimes the wallet simply has a flap of fabric that fits over the opening portion. It can have a snap closure, but many just hang free. A tote bag, another variant of the satchel is often open at the top. However, it may just be handbag related because it features handles instead of the shoulder strap.
Messenger bags, which have been carried for several centuries, required a tight closure, and are generally made of more weather-resistant vinyl, especially in modern times. Especially when you are in a hurry, by bike, horseback or even on foot, you do not want anything, especially letters, forms or money, leaving this form of a wallet. The modern messenger bag usually has a zipper closure to keep items secure.
The book bag, by contrast, is more insecure, with perhaps a single flap of fabric that can be easily moved or opened so you can quickly access your books. Of course, once again, without a secure closure, you may be at risk of losing books, assignments, and supplies. You may want to look for a book bag that has a fabric flap that can be zipped or closed. This will also provide some protection from bad weather.
The backpack is a derivative of the satchel, but instead of being worn over one shoulder, it’s worn across two shoulders, keeping the weight evenly distributed across the shoulders. This may be more comfortable for some. Of course, when the bag is carried on the back, you have to take the backpack off when you need something, which can be inconvenient.
In recent years it has been suggested that children using both backpacks and book bags may be inhibiting their growth and creating later spinal and back problems. The weight of carrying a lot of books can be burdensome, especially for young children. To this end, many children now have rolling backpacks, just like rolling suitcases, which do not create shoulder pain or back problems. Still, some kids and adults prefer the backpack as more convenient, and getting a rolling backpack down a crowded school hallway can be a chore.
