The earth is composed of 75% water so FIELDCRAFT took considerable thought and effort into developing our SEA WOLF waterproof duffle bag engineered to operate in that environment. Waterproof main compartment not only withstands water but can be fully submerged in 5 feet of water and keep your contents dry thanks to our waterproof zipper and High Frequency Welded Seams. Loaded with MOLLE webbing, compressions straps and 'D' rings providing countless configuration possibilities to stow gear for all outdoor activities and can be secured to boats, kayaks, canoes, trucks and even attach to other SEA WOLF bags to daisy chain them together to keep your groups bags organized. Our bags also contain a free-floating secondary waterproof pocket and two mesh end pockets to further organize and secure gear and electronics.
