When I started going away for a few weeks at a time camping off bikes , I found the tent was always wet either on top or underneath , never dryable so it goes into its own Ortlieb waterproof bag and sits across the rear between the panniers ,
View attachment 495480as it simply doesn’t do putting the tent stuff sack into a a pannier as it sets out all the stuff around it .
If you get a few wet days it’s impossible to dry it so stuff it wet , put it up wet ,, and just sponge the floor dry , the interior inner seems to dry out quite quickly once it is put up . ( Hilliberg )
