Best School Backpack:s High Sierra Powerglide Backpack Charcoal
I've had this backpack for about 7 months, and in that time, I've really put it to the test. I stuff it full and walk it a total of about 3 miles to school and back about 3-4 times a week. It held up in fall - wheels right over all those leaves that my old backpack used to just drag. It held up in winter - great on ice and packed snow; it works okay in slushy snow, but starts to drag a pile of slush when it gets really thick. I can't believe how durable the backpack is! It's very large, so I try not to wear it on my back too often, but it's comfortable when I do. I have trouble finding adult-sized backpacks with straps that tighten enough to fit comfortably. These adjust perfectly to my size. I haven't tried flying with it - it looks like it might be hard to fit it under the seat in an airplane. It should fit in the overhead compartments without any problem, though.
The issues some people have had with the small front media pocket isn't really a problem for me. I think the zipper positioning is due to a seam issue - since the pocket is adjacent to the second main compartment of the backpack. I walked 1.5 miles with it unzipped and my ipod and lip gloss didn't fall out. Just don't stuff that pocket too full, and it should be fine.
My only complaint is that the wheels are starting to show some wear (as I expected considering how much I use it), and I wish there were some way for me to just buy new wheels and change them out.
