It holds so much and it is nice and thick not flimsy. I carry my books back and forth to school in it and they are heavy. This bag totes them easily and it's sturdy and stitched well. I use to sew in a factory 13 years ago. In fact I was a senior lead and supervisor for the company and worked there for 31 years. I'm retired now but I can vouch for how well this is made from an expert point of view. The best part is I get to show off my love for Moondance magik and refer people to them! They reward nicely for referrals!
