Review: This was better than I expected. - This was a great investment. The backpack is shiny, and the straps are adjustable. Which is a good thing since I'm a tall gal. It's a decent size and a very comfy fit. At first, I was nervous that I couldn't wear the backpack with a jacket on, but it fit perfectly. I love the inner pockets and design. The quality is excellent, and the shipper was kind enough to put school supplies inside. I think this bag is worth every penny.
Review: Perfect for slim folders and laptops - Perfect for carrying folders, laptops and iPad. All kept protected and no bending of files or books. Straps are adjustable and comfortable with weight distributed nicely.

Le encantó a mi hija, por ahora es una puntuacion casi perfecta, porque llegó sin la base de la mochila, una pieza rectangular que va en el fondo del compartimiento principal, haré un overview a final de año
