I'm not sure if A.P.C. is really considered best-in-class for any specific product, maybe affordable raw denim, but they sure do a great job overall as a brand and a collection. It's one of the few brands that can't do much wrong and seem to effortlessly do a lot of right. Their latest version of the weekend duffle comes in a full grain leather. The classic shape takes a fair bit of leather to get the job done and with the subtle branding stamp, good size for it's use and perfect colour, it's a great looking bag. Without actually feeling the leather and putting it to use I would say it's one of their better bags in my opinion. The detachable shoulder strap, nice looking handles and satin lining are as they should be, so as long as the bag holds up it's only going to look better and better.
