I have to update this rating after 3 months of use and 1 plane ride. I love the drop bottom duffle bags. The zipper on the bottom split during my travel to Baltimore. Fortunately I did not loose anything. But now I am in the position of getting this bag fixed or  buying a new one to go home in 3 days.  The overall shell material is good quality.  The rest on the end helps it to stay upright.
