Insulated Fish Cooler Bag with Flat Bottom — 45QT / 42L

A compact flat-bottom fish cooler bag that stands upright on deck and keeps your catch cold for 24–36 hours. The Buffalo Gear 45QT is built from heavy-duty waterproof tarpaulin with heat-welded seams — tough enough for rocks, fins, and a full day on Lake George. At 5 lbs it's easy to carry by hand or over the shoulder, and folds flat with a buckle closure when you're done.

• 24–36 hour ice retention — 0.5" thick high-density closed-cell insulation tested in summer conditions
• 100% leak-proof — heat-welded seams and heavy-duty waterproof tarpaulin; blood, soil, and stains wash away easily
• Flat bottom — stands upright and stable on any surface; folds flat with buckle closure for compact storage
• Screw-on drain valve — tighten for leak-proof protection; loosen for quick, controlled drainage
• Lightweight & portable — 5 lbs; hand carry or shoulder strap; fits easily in your boat or vehicle
• 2 colors: White, Gray
