Rugged hard cooler
YETI Tundra 45
YETI's robust construction and thick enclosure suit repeated outdoor use. GearLab's testing supports its durable cooler role when strength matters more than getting the largest capacity for the lowest weight.
Why it ranks here: First for demanding use and robust construction.
The tradeoff: Heavy; model number is not the internal quart capacity.
