I bought this duffle because I have a 3V sling pack that I really love (awesome backpack) I love this duffle too. Great complimentary to my Tasmania luggage. Fits right on top of the small carryon roller and secure handle over handle seems like one piece. Very well made and the way its made also allows me to secure it using a corded bicycle combination lock. I keep it on the bag. Allows me to take it anywhere confident of its theft deterrent. Probably as good as the Kiss bags that cost much more and have feminine appeal. I just don't need to appeal to that side of me at this time.
