31QT Fish Cooler Backpack, Kill Backpack

Overview

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.

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.

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

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

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

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

Note: The zipper is water-repellent but not fully waterproof. The bag will not leak unless turned upside down.
