The Yeti Hopper 20 Cooler has the same ice-for-days performance as more traditional Yeti coolers but in a mobile design that allows for easy transportation. The shell of the Hopper may seem soft, but we assure you that it's tough as nails. Completely leakproof, the Hopper is made from the same materials used in high-performance whitewater rafts. Welded seams make for a bombproof construction and the Hydrolok zipper provides a water and air-tight closure. All this means that whatever you decide to put in this cooler is going to stay cold for days. Transporting the Hopper is easy thanks to a removable shoulder strap and two easy carrying handles that are triple-stitched to handle the heaviest loads. Six D-ring attachment points let you secure the cooler to you ATV, truck bed, boat, or whitewater raft securely and easily. The front of the cooler features Yeti's Hitchpoint grid system, which allows you to easily attach the Hopper Sidekick (sold separately) to the cooler. The antimicrobial lining of the hopper will keep it smelling fresh. This thing will easily hold either 12 cold ones or 20 pounds of ice.
