The Buffalo Gear 48"x18" Fish Cooler Bag is a mid-to-large kill bag built for offshore fishing, kayak fishing, and tournament anglers who need a reliable leakproof solution. The standout feature: a fully airtight, waterproof zipper that locks in cold and contains fish blood and water — unlike standard fish bags with water-resistant-only closures. Double-layer waterproof tarpaulin inside and out with heat-welded seams and a puncture-resistant exterior. Half-inch closed-cell foam insulation keeps your catch cold for 48+ hours. Screw-on drain plug for clean meltwater drainage. Folds flat when not in use. Available in White and Gray.
