Canyon Coolers Prospector 85 Quart Rotomolded Hard Cooler

The Canyon Coolers Prospector 85 is an 85-quart rotomolded hard cooler built for remote overlanding expeditions, extended multi-day river runs, and big-game hunting trips where keeping food and ice cold for the long haul is non-negotiable. Its straight-wall, low-profile architecture fits mid-size truck beds, SUVs, and standard 12-foot raft frames, and it is available in three colorways: Sandstone, Diamond, and Azure Blue.

Insulation That Works Under Pressure

The Prospector 85 uses extra-thick, pressure-injected insulation paired with a heavy-duty foam lid seal. Pressure injection fills the cooler walls completely and eliminates air voids that would otherwise let heat migrate in, the same reason this construction method is standard in high-performance coolers used in desert and backcountry conditions. That matters when you are three days into a river canyon with no resupply and no way to restock ice.

A Shape That Works With Your Rig, Not Against It

The Prospector 85's squared straight-wall design eliminates the tapered or rounded corners that waste usable space inside a truck bed or raft frame. The exterior footprint is 33 inches by 16.625 inches at the base, sized to sit flush and stable on washboard dirt roads without shifting. For raft use, the cooler requires a minimum bar-to-bar frame clearance of 17.6 inches and is designed around standard 12-foot raft frame dimensions.

The zero-clearance hinge lets the lid open fully even when the cooler is pushed directly against a truck cab wall, boat hull, or stacked gear. That matters when you are reaching in for food without rearranging your entire load. Integrated front and rear rigging lip slots allow cam straps to run completely over the top of the cooler, securing it to a raft frame or truck deck without blocking lid access.

Drain Access From Any Angle

The Prospector 85 includes both a front and a side drain plug, each threaded to accept a standard garden hose fitting. Having two drain positions means you can clear meltwater from whichever side of the cooler is accessible, which is useful when the cooler is lashed into a raft frame or wedged against a truck sidewall and rotating it is not practical.

Rotomolded Construction and Lifetime Warranty

The shell is rotomolded from UV25 to UV40 impact-resistant kayak-grade plastic, the same material class used in whitewater kayaks for its resistance to cracking, UV degradation, and hard impacts. Canyon Coolers backs the Prospector 85 with a lifetime warranty.

Specifications

Who This Is For and Isn't

The Prospector 85 suits overlanders, river guides, hunters, and anglers who need a large-capacity hard cooler that fits a mid-size truck bed, SUV cargo area, or standard 12-foot raft frame and can handle rough terrain and extended trips. At 85 quarts, it holds enough for a field-dressed deer or a week of provisions for a family.

Wire cooler baskets, snap-on seating pads, cooler locks, and the Prospector Side Table are compatible accessories sold separately and are not included. The Prospector 85 is a hard-sided rotomolded cooler; buyers looking for a soft-sided or collapsible cooler should consider a different model.

Common Questions

Will the Prospector 85 fit a standard 12-foot raft frame?

The Prospector 85 is designed for standard 12-foot raft frames and requires a minimum bar-to-bar clearance of 17.6 inches. The base footprint is 33 inches long by 16.625 inches wide, and integrated front and rear rigging lip slots allow cam straps to run over the top of the cooler without blocking the lid.

How does the dual drain plug system work?

The Prospector 85 includes both a front drain plug and a side drain plug, each threaded to accept a standard garden hose fitting. Having two drain positions lets you clear meltwater from whichever side of the cooler is accessible without unlashing or repositioning the cooler in your rig or raft frame.

Can the lid open fully when the cooler is against a wall or packed gear?

Yes. The Prospector 85 uses a zero-clearance hinge design that allows the lid to open completely even when the cooler is pushed directly against a truck cab wall, boat hull, or stacked camping gear, so you can reach the full interior without rearranging your load.

What accessories are compatible, and are they included?

The Prospector 85 is compatible with Canyon Coolers wire cooler baskets, snap-on seating pads, cooler locks, and the Prospector Side Table system. None of these accessories are included with the cooler; all are sold separately.
