Flat Bottom. 22oz Tarpaulin. 24-36 Hour Ice. Stands Upright on Any Surface.
The Buffalo Gear 37QT Fish Cooler Bag is a mid-size fish cooler bag built around a flat-bottom design that stands upright on any surface — boat deck, dock, or tailgate — without tipping. Heat-welded seams and heavy-duty 22oz double-sided waterproof tarpaulin keep leaks and odors locked in. Half-inch closed-cell foam insulation tested at 100°F (38°C) keeps your catch cold for 24–36 hours. Folds flat and buckles compact when not in use. Available in Gray and White.
