Insulated Fish Cooler Bag — 40×18", Airtight Zipper, 48hr Ice Retention

A mid-size fish cooler bag that punches above its weight. The Buffalo Gear 40" bag features a true airtight zipper — not just water-resistant, but fully sealed — keeping cold in and fish blood contained. Double-layer 22oz waterproof tarpaulin inside and out, 48-hour ice retention, and it folds flat when you're done. A solid choice for a full day on Lake George without the bulk of a hard cooler.

• 48-hour ice retention — 0.5" closed-cell foam insulation keeps your catch cold through full-day and overnight trips
• Airtight zipper — fully seals cold in and contains water and fish blood; a step above standard waterproof zippers
• Double-layer 22oz waterproof tarpaulin — inside and out; heat-welded seams prevent leaks and handle sharp fins and rough use
• Screw-on drain plug — prevents spills; fast, controlled meltwater drainage
• Folds flat — stores easily in boat lockers or truck beds; no bulky cooler needed
• Easy to clean — 22oz polyester lining rinses clean in seconds
• 3 colors: White, Gray, Blue
