The EGO 100L Tactical Dry Gear Bag will protect your gear from whatever mother nature may throw your way. This bag is constructed using high-performance waterproof TPU fabric that is stronger, lighter, more flexible and abrasion resistant than PVC fabric. It features a roll-top with zipper closure, welded seams, Kryptek camo technology, molle loops for external tool management, and a contoured shoulder strap. In addition, the 100L model comes standard with a removable backpack strap system for hands-free carrying. The harshest weather conditions are no match for the EGO 100L Tactical Dry Gear Bag. Mother nature...bring it on!
