The Over Under Hull Bag by Allen is the perfect hull bag for those that like to shoot single rounds of trap or skeet. The outside pocket is made from durable molded EVA and holds one standard size box of 2-3/4 inch 12 gauge shells. The hull compartment holds at least 100 empty shells and unzips at the bottom to empty. Two D-Rings are attached to the outside of the hull bag so you can attach the accessories that you need. Two elastic loops are attached on each side of the shell box compartment where you can keep extra shells or choke tubes.
