This internal system allows for increased organization in your Thunderhead Submersible Sling Pack. The padded walls and floor of the insert offer protection against bumps and vibrations for camera bodies, lenses, fly boxes and other valuables.
Great for organizing the Thunderhead Sling. Wish the middle portions were a bit more flexible so it didn't make the bag so rigid, but you can't argue with the space. Definitely a great addition to your fishing bag!
Adjustable dividers. I was still able to use the zippers and side storage in my thunderhead sling.
