Living somewhere as wet as Seattle, I’m always interested in ways to keep my stuff dry. So, I have started to repurpose those old coffee bags as dry sacks. Small ones to be sure, and I wouldn’t submerge them, but as an extra layer of protection for socks and electronics in your backpack (or trunk) they work great. Just make sure to wash them out thoroughly so the critters don’t want to get into them.
Hopefully some of you find this useful, and if you have any other clever uses I would love to hear them.
