So I've been using a Timbuk2 messenger bag (medium Classic) for my MBP and my iPad Air 2, but I recently purchased the 12.9" IPP with the Logitec clamshell case with backlit keyboard (which I love btw..."it's so choice. if you have the means, I highly recommend picking one up" - FB) and the extra sleeve is not large enough to hold the IPP. Anyone out there have a suggestion for a dual laptop bag with TSA approval that isn't the size/weight of a large toddler with pizza and gummy bear addictions? Daily commute bag that travels well and still has a bit of room for accoutrements? I'm open to backpacks or messenger bags - just not finding anything that wows me.
