Insulated Fish Cooler Bag with Flat Bottom — 37QT / 35L

A mid-size flat-bottom fish bag that bridges the gap between the 27QT and 58QT in the Buffalo Gear lineup. The 37QT holds more than a day's catch, stands upright on deck, and keeps ice cold for 24–36 hours — tested at 100°F. Solid choice for a full day on Lake George without committing to the larger bags.

• 24–36 hour ice retention — 0.5" closed-cell foam insulation tested at 100°F (38°C); keeps your catch cold all day in the hottest weather
• 100% leakproof & odor-free — heat-welded seams + 22oz double-sided waterproof tarpaulin; no leaks, no odors in your boat or vehicle
• Rugged & puncture-resistant — built to handle sharp fins, rocks, and hooks; rinses clean with soap and water
• Flat bottom — stands upright on any surface; folds flat with buckle strap for compact storage
• Built-in threaded drain valve — fast meltwater release without lifting the bag
• Padded handles + shoulder strap — hand or shoulder carry options
• 2 colors: Gray, White
