Bought this for using at work, so I can't speak to how durable this pack is as it really only sits in my car and then sits in my office. But it's spacious inside, has lots of different sized pockets which lets me organize all my various things, and I like the two water bottle holders on the outside. Like I said, I haven't tested the durability much, but about a year of daily use it's holding up great.
