This is the BEST TEACHER bag ever! If you are a teacher, you need this bag. I have been through many bags, and this one is the winner. It fits so much, and I love that it pops open upright so you can reach right in for your laptop, folders, books, etc. Since it is waterproof, I never worry about my work or students' work getting wet. It has just the right amount of pockets...and for a backpack, it is very stylish! If you are on the fence, don't hesitate to buy this bag. It is well worth the mone...
