The Berkley Jar Bait Folder is designed with the trout and panfish angler in mind. I deal for PowerBait, dough bait, Gulp, and Gulp Alive jar baits. The Jar Bait Folder is an anglers solution for getting tackle to the water. The shoulder strap provides a hands free method of transporting bait, tools and terminal tackle. The Jar Bait Folder also stows away into other Berkley model tackle bags.
