I just received this awesome little backpack for a reduce price in exchange for my honest opinion. It is really a cool backpack. It's pretty average in size, maybe a little on the small side. But it's really cool because it folds up into itself into a nice little pouch for storage. I love the 2 side pockets available that are perfect for water bottles. And the straps are super comfortable. They are made of a soft netting fabric so it doesn't give you that painful rubbing on the front of the shoulders, and it's breathable fabric so you don't get all sweaty in the heat. All in all, a nice backpack.
