in love with this bag! so many little compartments for storage. originally bought the Medium for my 15" laptop, which worked, but the opening was super snug for trying to get your laptop in and out quickly, it will put stress on the zipper and end seams and not to mention wear on the edges of my laptop so I traded it back in for a Large. Now, in and out, quick and easy! The buckle/latch deal will take some getting used to but they work but they stay put . I still prefer the click of a buckle, this would be my only complaint/gripe if any?!
