This is a very good quality bag; I think I've had it for two years now and use it almost every day, it shows no signs of wear at all.  My 15.6" laptop barely fits in it; I had a 15.5 when I got it and that was easier:)  But I highly recommend this bag, especially given the price, it's an excellent value.  Very durable and I imagine I'll use it for years to come.  Great for carrying books, going to the beach, or just everyday use.
