Looks like you are looking for a higher end one, but I bought this one and it is a really good looking minimalist daypack:

I don't know how long it would last but at $20 shipped I could keep replacing it. it is very light and comfortable too. It is big enough to carry a 13" macbook but nothing bigger than that.
Also there is no straps hanging at the bottom of the backpack on this one. I don't know why but that makes me happy. LOL.
