We have both the Anton sling (the very small one) and the Anton backpack. The backpack has lovely buttery leather but gets extremely heavy if you try to fully load it - and with the single strap carry it can press quite heavily on your chest and shoulder. It also looks quite different (in a bad way) if packed full and really looks best half full with the slouch of the flap. The closest cousin to this Anton backpack will be the Isar from Cote et Ciel (which we used to have as well) but two straps vs one makes a lot of difference in terms of load distribution. It's also a challenging bag to store - we ended up having to essentially store it half folded or it takes up too much space - so far no additional crease lines though.
Wouldn't recommend the Anton sling - the conical nature of the bag means it actually can't hold much despite looking like it could, and is a bit fiddly to use. Its proportions also can look weird on some body frames.
Anton backpack - agree that it does not look good when it is full. It sticks out way too much when it is full especially when worn. This bag needs to drape and slouch to a look good. I do not really find this bag that heavy but I usually wear it on the shoulder and holding on the strap. I find that’s the best way it looks, more casual and sporty.



Anton sling - same here, I think the proportions are not the best.
