I want to be able to swim with my rucksack. I have a Xenith 88 from Osprey. Lots of small lakes with small islands on them where I'm from, and I'd like to be able to swim out to them and set up camp on them.
I need a durable and waterproof bag I can carry around and shove my rucksack in. Will this do the trick? Can I actually drag this after me as I swim? Should I look for something else?
