The Sniper Waist Pack was designed to be attached directly to a belt and developed with direct input from Scout Sniper instructors. The design provides a product that won't be lost or discarded during an immediate E&E. The SWP storage provides enough ammo/food/medical supplies to make it home. The end pockets are open end to end. The next two pockets in our magazine pouches capable of holding up to 3 M4 Magazines, MRE's, or lifesaving equipment. The center 4"x4"x3" pocket can be used for a med kit, cleaning kit, or any other crucial items.
