These marvellous pieces of kit are great to stow away your neatly rolled up dry clothing then roll over the fixed plastic top and buckle up securely to keep your kit dry, then just as easy getting access if you've remembered which bag you've packed your socks in of course German pioneers Ortlieb offer these 100% waterproof medium density bag liners that we recommend you using for your side pockets (13 litre), daysack (35 litre) and bergen (109 litre).
