MAJOR DESIGN FLAW. Should've listened to other reviewers who said the zipper gets stuck on the inside fabric when compressing. I've literally spent a half an hour trying to unstick and back up the zipper only to get more fabric stuck. It's impossible. I even went ahead and lead with my finger when zipping thinking that won't happen to leave if I'm careful. Well it was. The frustration is not worth it. Even though they pack you rthings nicely.
