Perfect for cruises and the beach
I used this on my cruise and when I went to the beach. I put my shirt, phone, wallet, etc. In the bag and then ran the cable through my shoes and tied it around either a beach chair or a life guard tower. Perfect bag to keep valuables safe while snorkeling. I may get another, but slightly larger. This 3 liter one also fits perfectly in my backpack and I can run the cable through the spot for the water tube that connects to the bladder if you're using one of those. Just another way to keep your backpack connected to this travel safe.
