It's great, it has been adjusted accordingly. You can put as many things as you want. For example, if you don't want to fill it up, you can tighten the straps and it looks like a regular everyday school bag. For those who are afraid it might look too big on their back and stick out, I had this little issue too, and with the adjuster, it's simply the best one I have worn.

The best backpack I have ever held in my hands, and I have held many. When you wear it loaded, it feels like it's empty. Truly perfect.
