This roll-top backpack by Phantom Aquatics is a great option for a dry bag survival backpack. A pack like this could REALLY come in handy when things get wet and it’s easy enough to fold and store with an additional, larger capacity survival pack.

This bag is designed to safely float, so it’s a good choice for traveling by boat.

The large outer elastic storage space, as well as the mesh side pocket, allow you to store some gear on the outside of the pack. This bag also has two methods of sealing depending on what you’re trying to do with your pack.

The back panel is constructed with an air flow design to minimize the uncomfortable heat and stickiness that some waterproof packs can generate. Adjustable sternum and waist straps make this bag as comfortable as possible. I think the quality of the straps on this pack is what makes it the best waterproof option – as well as its more than fair price point.

If you want to be prepared for wetness and need to keep electronics and other sensitive items bone-dry, then consider adding this pack to your survival gear.

If a waterproof backpack is a little excessive for you, then maybe consider purchasing a highly packable dry bag to include in your larger capacity survival backpack.
