when I first saw the price of this pack I was a lil disgruntled but I bit the Bullet and bought it anyways. Best backpack so far, Plenty of room for all of my stuff whether it be for school, hiking or just biking around the city. Not only does it have compartments for everything but it has some hidden extras that some of those who bought this bag may not be aware of. the waist straps can tuck in to the lil side pockets kind of like a hole that was not stitched there all the way. The other hidden gem is the chest strap has a lil whistle that can be used if your lost in the woods and people are trying to find you. It's plenty loud as well. just some additional added features that the product description does not tell you. It is also a very durable material that takes allot to tear. Overall I'l glad I spent the extra money for this bag.
