Review is for the World Traveler 81T16-642 Duffle Bag, One Size, Black Blue Paisley.  I've used this for many trips in the past 4 months and never had a problem.  The zippers all work well and it has performed as expected. The side pockets are PERFECT for stowing your liquid bag on one side for TSA and book, earbuds, umbrella, etc, for quick access on the plane and transport. I used this as personal bag on top of my carry on and never used the shoulder strap so I cannot comment on the comfort or length. I love that the inside is all vinyl and easily washable if something is spilled. The outside front pocket has so many nooks and crannies for phone, Kindle, pens, paper, etc.  The inside is one big bag. I put in a pair of hiking boots, socks, travel maps, binoculars, 35mm camera, flashlight, books, fleece vest, and sweatshirt.  Basically the bulky things that take up too much space in my carry on suitcase. The strap that goes over the luggage handle is a little snug and if the bag is overpacked it can be a struggle to get it off and on. Also do not overpack since it will be hard to get under the seat in front of you.  This bag holds a lot of stuff and volume can easily get out of hand.
