I have read a number of times people comment that the Ristretto and Cafe bags look like they will let rain in around the edges of the flap.
This morning I got caught in some particularly heavy rain on my way to work. I had a small umbrella which kept my head and part of my front dry but when I got to work I realised the Ristretto on my back had got soaked.
And guess what? No water inside. Not a drop. Must be some kind of weird Seattle magic that makes the flap sit just in the right spot to look like it may leak but let nothing in.
