31QT Fish Cooler Backpack, Kill Backpack

Built for serious anglers who need extra space, the Buffalo Gear 31QT Fish Cooler Backpack delivers more storage for longer trips — perfect for kayak, boat, and shore fishing. Combining large capacity, leakproof protection, and hands-free comfort, it’s made to keep your catch fresh all day.

100% Leakproof & Waterproof

Made with double-sided 22oz heavy-duty tarpaulin and heat-welded seams, this backpack forms a sealed chamber that prevents leaks and odors — even strong enough to hold live fish.

Extended Ice Retention

Thick 0.5-inch closed-cell foam insulation keeps ice solid for 24–36 hours, ideal for full-day or overnight fishing trips

Rugged & Durable

Reinforced outer shell and base resist cuts from rocks, decks, and fish bones, tough enough for kayak or offshore conditions.

Quick Drain & Easy Clean

Equipped with a screw-on drain plug for fast meltwater release. Smooth interior wipes clean in seconds — no heavy cooler needed.

Hands-Free Convenience

Padded shoulder straps, reinforced top handles, front pocket, side loops, and rod holders keep your gear organized and easy to carry anywhere.
