Tough exterior shell stands up to drops on rocks. Removable center panel adds to capacity. Holds 72 large/medium flies (sizes 2-14).
Dimensions: 6" x 4" x 1-1/2".
I have two other SA boxes and love them. This one, however, has been made TOO waterproof. I have three streamers whose hooks have rusted and broken because no air can circulate within the box to let them dry. Shame on me for not letting the boxes open after I get off the water. Every time I pull the box out of my vest, there's condensation on the lid. I'm going to drill some small holes in the lids to allow at least some air to move around and hopefully keep my hooks in better shape!
