The YETI Tundra 110 is great for river rafting, because we built it specifically for rafters. Itll take on the rapids with you again and again thanks to its highly durable roto-molded polyethylene construction the same method used to make whitewater kayaks. Its big enough to hold all the supplies youll need for a long trip down the river, and has extra-thick walls and up to three inches of insulation to keep them cold the whole time youre on the water. But admirers of the Tundra 110 arent limited to the rafting community its durability, unmatched ice retention and clever features like a leak-proof gasketed drain and self-stopping hinges make it a favorite for hunters, boaters and campers alike. Its also preferred by those who regularly journey into bear country because of its official grizzly-proof certification.
