This bag is very nice and high and the Macbook 13 "fits in perfectly and is extremely well padded and weatherproof protected. It has relatively little storage space for accessories but a few cables and the power supply as well as a great Sennheiser headphones fit in. I was then quite surprised how much Krim Krams fits in the pocket. But it does not replace "Every Day" bag. I use them exclusively for the Mac to transport. If you put on Ästetik value I can recommend it. If you want to store a bottle once it looks bad out. 3.5 "external HDD does not look good. A 2.5 "HDD, however, is again perfectly fits in your pocket. A few A4 sheets go loose in. The handles can be hidden in the side pockets when you want and the strap is high quality and not bulky. All in all, a very nice bag.
