I had to decide on the long search for a good weekender and had to be between the Duffel The North Face and Patagonia. The choice was then, among other things because of the sustainability of Patagonia.
The product does what it says, I have it already retinues three times a week in use and am with the bag. No problem at all, neither the rain nor the baggage handling at the airport you could wear what. The bag is largely sealed even in heavy rain, very close it can not be because of the zipper.
I have the 60L version what for everyday life (Gym) is more than enough. Even for a small trip over 4 days it is not too small. It is very handy and provides substantial protection.
I am very pleased and will bring me so for Urlaubsreien still a Black Hole with 120 L.
