Tacworld 3 Day Assault Pack Military Backpack is designed to hold enough gear for a 3-day mission. Made from rugged, water-resistant nylon, this pack keeps your gear secure and dry. The shoulder, sternum, and waist straps adjust to provide a custom fit. The yoke system in the shoulder straps distributes weight evenly and thick padding increases comfort. Four pads on the back ventilate and support, while tacky rubber prevents the pack from jostling around when you're on the move. The spacious main storage compartments provide ample storage for big items, while smaller zippered pockets, key chain fobs, and pockets with retention straps organize smaller gear.
