I've had this bag for four years, have used it almost every single day, and it practically looks brand new. I carry my books and equipment back and forth from work. If I'm heading out of town, there is room for a laptop, change of clothes, a book or two and necessaries. Despite the ample amount of room inside it does not look or feel bulky when I am carrying it. In fact, after first pulling it out of the box, I was quite surprised the first time I opened it to see just exactly how much it could hold. I did quite a bit of research before purchasing and I couldn't be happier with the selection. Would definitely buy the same again if this one wouldn't last forever like it seems it will.
