Katherine N.wrote a review of Patagonia Half Mass Bag - 1343cu in on August 29, 2012
Definitely a great bag. Fits my 13" laptop, and could probably fit a 15". The waist strap is essential for biking to school! And so much more stylish than a backpack. I wouldn't mind a little more room, but I can fit a whole day's essentials (lunch, notebooks, computer, jacket, nalgene, mug) without issue.
