My local store had one double swagger and I was glad to see it. I was curious about it myself. It looks a little wide on the models but not that wide in person but guess it depends on you! I'm not a stick model size but I'd say average. I think the measurements online are off. I think the center section measurement is the same as a regular rogue. I think the measurements online don't include a measurement for the side part that juts out so it is a bit wider than the rogue. I don't have a job where I go to the office every day now so it is too structured for me on a non-work basis.
I was surprised I liked the Cooper, honestly. Even though I consider the Cooper a more structured bag I'd mostly carry to the office, I'd still buy it before I think I'd consider the double swagger. I like the simplicity of the Cooper and the minimal design details. The two straps that close the bag may drive me crazy but if I keep them in the back section while I'm out and about, it will be OK and then i can use it to close the bag when I want. They do add a nice design detail.
I like the Bandit for casual days. I think oxblood may be my next one unless I can find a steel blue one that I believe was sold out last SAS. I have it in black w/ metal tea roses, chalk, dark turquoise, oak suede, dusty pink with tea rose side and the multi colored one (goldenrod, oxblood and a bright blue color). I like being able to mix and match the inner pouches amongst my bags to create a whole different look and especially using the tea rose pouches.
