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‘’ 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.
