Insulated Fish Cooler Bag — 48×18", Airtight Zipper, 48hr Ice Retention

A mid-to-large fish cooler bag with a true airtight zipper — not just water-resistant, but fully sealed to lock in cold and contain water and fish blood. The Buffalo Gear 48" bag is built from double-layer 22oz waterproof tarpaulin inside and out, with heat-welded seams and 48+ hour ice retention. Folds flat when you're done. A solid step up from the 40" when you need more length for bigger fish on Lake George.

• 48+ hour ice retention — 0.5" closed-cell foam insulation keeps your catch cold through full-day and overnight trips
• Airtight waterproof zipper — fully sealed; locks in cold and contains water and fish blood unlike standard waterproof zippers
• Double-layer 22oz waterproof tarpaulin — inside and out; heat-welded, leak-proof seams handle sharp fins and rough use
• Screw-on drain plug — no messy spills; fast, controlled meltwater drainage
• Folds flat — no bulky hard cooler taking up space; puncture-resistant exterior built for the water
• Easy to clean — 22oz tarpaulin lining rinses clean; just rinse and dry
• 2 colors: White, Gray
