I have absolutely no issues with this bag. Very nice bag from one of my favorite companies. I am using it with my 15" rMBP and it fits beautifully. This bag has all the room I need for my laptop, iPad, iPad Mini, Logitech m570, LaCie Rugged Thunderbolt and my Kindle PaperWhite.

I bought my GF the medium size bag for Christmas for her MBP and she uses it every day. Quite roomy. The large must be a beast.

Favorite features of this bag; Brick storage pocket in the bottom of the bag, Napolean pocket and Velcro silencers.
