You can stuff it and stuff it and there is still room. I am a forestry student and I love the way I can put everything I need for all my classes in one bag. The 2 side pockets are awesome for my GPS extra batteries, whatever. I can go on and on but this is the bag you need. And once loaded (heavy) it is still comfortable on the shoulder due to the great padding on the straps. And the price is 1/2 of the other brands with less room... I am so glad I read reviews on this one before I bought it..
