Historically, shoulder bags like these would be used to carry the tools and equipment needed to keep a black powder gun running. Now a shell bag could come in handy for anyone looking to expand their carrying capacity a bit by having a big pocket to carry essentials at their fingertips. Shell Bags could be used by hunters to carry extra ammo, or hikers as a ranging bag to keep stuff dry. It also makes a distinctive and very functional purse. They work great for disc golf discs, or add a Plano® Box and head out fishing.
