Even though this say's its for a 15" Mac Book Pro, I use it to carry my 13" MBP and my Ipad. There is some extra room in the laptop sleeve but the padding is exceptional and the velcro strap is sufficient in securing it in place. It also has two other internal pockets for keeping my odds and ends organized, with room to fit some magazines, a notebook, small pencil case, a travel snack, a book, my travel kit (ear plugs, eye mask, socks), sunglasses, and some other miscellaneous stuff. Also really love the outside pocket placement, it's easy access to my wallet, iphone and travel documents. I highly recommend this bag for travel and everyday use. It's super durable and holding up extremely well after a lot of use, even the color. The blue is really great in person.
This bag is brilliant, and multipurpose. Its great for my everyday bag, going to work and gym. The fold over top allows me to fit my sneakers and gym clothes if I really need or fold it over and then have just the right amount of room for work. (Laptop, moleskin, iPhone, iPod, headphones, and magazine for the subway commute just perfect.) For when I'm traveling as my personal carry on - I love that it fits both my mac book pro and my iPad with the front pocket super key for things I need to reach easy (wallet, plane tickets, iPhone). I thought the color might be too much but I absolutely love it, how many black bags does one person need.
