[Request] Spacious Backpack $100 or Less

Any recommendations for a backpack $100 or less? I might even go to $150 depending on quality. Currently in medical school and have had a Swiss Gear since highschool. It's spacious with ample compartments but I've already had to use the life warranty since the side pockets (that hold bottles) ripped along with the zipper tread.

On the second one and had to sow the tip after it ripped near the zipper and the zippers don't completely close.

Thanks!
