Dry bags are great – little water tight bags that you can used to both organise your stuff in your backpack and to keep it safe and dry. I have these ones from sea to summit in a variety of sizes:

The different colours are helpful, but once you’ve bought more than one of each size, you might know something is in a bag, but which one?! We are super proud of this nifty tip – a bit of ‘decoration’ with a permanent marker and there’s no more confusion. Particularly if the doodles match the thing in the bag eg the footprints oneonce had clean socks and change of shoes in, the one with the spirals had things like charger wires and headphones.

Hope this tip helps you pack for your next adventure.
