One of my favorite bags from the Porter collections is always the Boston bag. The duffle bag seems to always come with a slightly different touch, whether it's materials, shape or design. The only thing that really seems to stay the same is that it does remain some form of a duffle bag. After recent experiences I have begun to appreciate the science of product design a lot more. Also I've noticed a lot more products that don't have the kind of care and attention to detail you'd hope to find. Anyways, Porter does seem to put thought into their products. They are made for a reason. This narrow shape and long handle straps makes the duffle extremely narrow, and really ideal for short hauls while being able to pack a reasonable amount of stuff. I have found short handles really can cause an annoyance when on the road and you need to rest your arms. The duffle is of course available in Japan here.
