Most people have a lot of school books, and sometimes you just can't leave everything in your locker. What do you use to carry your stuff around in? Mine wasn't fancy. It was a pretty deep blue, with black straps. Only the back was blue, but that was the only part that mattered.
I don't remember any other backpacks before that honestly.

My backpack didn't stand out that much either. I don't exactly remember what I used to wear, though I do remember switching to one with a shoulder strap when I entered university. I didn't quite like the change and it couldn't be loaded heavily, so I was quick to discard it.

As of late, I've been using a Harley Davidson backpack, because it has amazing resistance and can be loaded up heavily without any kind of issues. This bag has been at our home for probably a decade or more, and it's still in very good shape.

I've also started to use a much lighter, sports-like bag with thin cords instead of straps. I use it whenever I need to carry with me just a couple things, like the water bottle I carried for my dubbing classes. Also, it's very small and I could put my jacket over it with ease, which comes in very handy as I usually take off my jacket when entering places and that way I don't have to worry about difficult maneuvers.

Mine is a black backpack that I've been using since my freshmen year of high school. So about 4-5 years, and I still use it in college, though it has shown it's wear, one pocket's zipper is broken.

I've had a black Jansport bag for the longest time - probably got it sometime in high school, so probably about 6-7 years now since I'm finished with college in just about a year. I wash it every 6 months, and it has withstood weights and trials I don't think any other backpack could do. Must be made of adamantium or something.

For going to the gym or when I travel short-term, I use the same bag - I have a standard Adidas gym bag. Fits a ton more in there than you'd expect.

I use a large black backpack with a little bit of light blue on it. It is a really nice backpack because it has a small pouch on the side that I use for pencils. It has a big pouch in the back that I use for carrying somewhat big things, such as snacks. That comes in handy when I need to hammer out homework in my college's library, and I don't have to go in another building to buy a snack! My backpack has a large pouch for all my books and another large pouch with a slot perfect for my humongous laptop.

I carry around a lunch bag to carry my different diabetes supplies I need as well as snack in case my sugar goes low I've often said my bag is my life and I honestly do believe that since without it I'm kinda dead.

It honestly depends on the day's workload and how I scheduled it. I have around 3 backpacks, a larger swiss army for days that I need a hundred binders and folders, my smaller blue pack for sports related classes and changes of clothes, with room for some folders. And finally my laptop bag, so I can obviously hold my computer and couple extra things. Call me excessive but I have a system worked out.

I used to have a Kipling backpack in elementary school, which was like the big thing to have as a kid because of the little Kipling monkey that their products came with.

When I got to Middle School, it was apparent that the Kipling bag was both too small and a bit childish, so I got an Eastpak backpack instead. That trooper carried all my stuff for years, and I still use it occasionally when I'm staying somewhere for a few days.

I don't need to take a lot of stuff with me to work. I only really bring a water bottle, some snacks (I have the ability to go home for lunch), and some other smaller things like wallet, keys, phone, my work badge, etc. I have a shoulder sling bag that I bring with me. I got in for a reasonable price at the army surplus one town over. I didn't want anything cumbersome especially with bringing such a small amount of items to work. I don't have a locker but the bag is actually small enough to slide into the bigger drawers in my desk.
