This is an item most kayak fisherman isn’t going to think they have a use for immediately. What’s nice is you don’t have to use the entire volume and the pack will become small enough to be useful for many applications. The great part is should you decide to go on an overnight trip or need a large watertight pack you’ve got it. It’s great for many fishing applications. Anywhere you need to have a bunch of gear and/or clothing stay dry. It’s a necessary piece of equipment for overnight kayak fishing trips especially when floating down a river. It has a purge valve which is very nice for getting excess air out.
