Awesome bag but I found it to be smaller than I thought. I haven't felt any additional strain on my back and I use it all day long for my job.

If the back had more padding I would recommend it for everyone. You can tell the material is strong and not cheap so it's definitely worth it.

I bought this backpack for my son to take to school, but he carries it like a suitcase now! It's also really good for airplane travel.
