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