I commute to and from the city on a regular basis, and I needed to upgrade from my chrome mini metro. I'm a 5'5" woman so I was looking for a bag that I could lug my 15" MacBook Pro and other EDC (e.g. water bottle, notebooks, books, etc) and would protect it all from the elements. The weather has been a bit frenetic lately (to put it lightly) and this bag has been great about protecting all of my belongings. The bag is also lightweight and stylish, and I don't worry about it getting scuffed by normal urban wear and tear.
