I bought this without expecting it to be my favorite.  I liked the security features and was going to be overseas so thought it would be a good idea.  I really enjoy everything: shape, size, construction, convenience, quality.  When I returned home, I used my 'favorite' everyday bag and 2 days later the zipper pull came right off and made it impossible to close.  Since I had this available, I put everything back in it and have been using it for every day.  This is an excellent product.
