    • Great Quality Backpack for School
Color: Black Size: One Size
My daughter loves this backpack and uses it every day for school. The quality is really good, the material feels durable, and it has plenty of space for books, school supplies, and even a laptop. The straps are comfortable and it still looks great even after daily use. Definitely a great backpack for school and worth the price. ... show more

    • Fits A lot!
Color: Black Size: One Size
Came as expected! As a junior in high school with a heavy course load and 4 AP's i have a bunch of binders per class that are a tight fit in a regular backpack. In this it fits everything and still leaves room for other stuff like my pencil pouch, makeup bag, brush, calculator and other miscellaneous items that i had to shove and force into my old bag. In addition the material is pretty thick and high quality so its durable and withstands the weight of my textbooks too on some days when i have to bring it to school. The style is like any other back pack, though I've noticed the size def helps with the weight a lot better without straining or leave my shoulders as sore. I do wish it was a lil cheaper as i paid out of pocket from the little money i make from my job and considering it is necessity for all students, however, for the brand, quality and the spacious room u get I think it's overall worth it ... show more

    • Outstanding backpack!
Color: Blue Dusk Size: One Size
I love this backpack! It is durable, a lovely color, and I use it daily. As a teacher, I constantly lug around papers and notebooks. I can easily put everything into this backpack, as well as my computer. It is comfortable to wear and has easily adjustable straps. I use the little top pocket for protein bars and small snacks, the back pocket for folders and my computer, and the others for my personal materials and student work. It is a perfect backpack for me. ... show more

    • Large storage capacity, adjustable straps, perfect for the whole family.
Color: Black Size: One Size
Had to buy this larger jansport to accommodate our 4th graders 3 inch binder, lunch box, and water bottle. It easily fits everything we need it so. Straps are adjustable. Quality is great. It is a good value because jansports last forever. Machine washable. We are a jansport family- highly recommend. I do wish jansport had more design options for boys. They have so many cute “girly” designs but hardly anything for boys. Can you team up with NFL or college teams to do some sports logos, or maybe just sports themed backpacks in general would be a great option! ... show more

    • Heavy duty and long lasting
Color: Black Size: One Size
Great backpack, I buy my daughter the same name brand every year. In the past, her backpack had to be replaced towards the middle of school year, but jansport backpacks are very adorable and last all year.

    • Great but broke. I bought two!!!
Color: Pastel Lilac Size: One Size

I love this JanSport !! It is very practical for kid through 3-9 grade. I also love that when the younger kids are playing in the mud or water it is easy to clean and is water resistant. This backpack is also so easy to pack a water bottle, a lunch box, a computer, some notebooks and much more. The only thing I don’t like is this backpack is over priced though worth it. Also the zipper broke after 2 years of use!!! Then we got it fixed a Taylor place. Over all if your looking for a bag for your kids, with practical uses and more. Then this JanSport is for you!!! ... show more
