Yeti Coolers are one-piece, rotational molded plastic made as the same indestructible material as whitewater kayaks. Each features a rubber, freezer-quality gasket that seals around the entire lid. This seal, combined with the ample insulation, assures you of maximum, long-term ice retention. The lid hinge on a YETI is molded right into the cooler. A full-length aluminum rod connects and holds the body and lid together. And, hinge-stops are molded into the lid, so the hinge can't hyper-extend and break. YETI Roadie coolers have the same hard-wearing features and insulating qualities as our top-of-the-line Tundra coolers, with a stainless steel handle made for tossing it around.
