Query: It's great.

I bough this guy as a replacement for my old jansport backpack that died after about seven years (I tend to destroy things). I use this for everyday use in college. I like the design, but most importantly I picked jansport because their products tend to last a long time. It's a great backpack. I'd recommend it especially if you like no-nonense backpacks like I do.
