It was fine - a little damp at the very bottom due to me resting it on the ground now and again, but mostly dry despite the heavy rain and wind. I think in the worse conditions most bags would get a little moist due to water running down the back between body and bag. I'm very happy with it even though it's a little heavy for a day bag - it fits a lot in.
Ahhh bad Dibble
.... did you see a sheep wearing the original Dibs hat that was lost up there 10 months ago?
Dibble I am disappointed
