THE HYDRATION HERO YOU NEED TO KEEP YOUR WATER ICY-COLD WHEN THE WORKDAY GETS SCORCHING HOT. The YETI® Silo® 6G is what a water cooler should be: a hardworking hydration station that keeps water cold for hours, tough enough to take a tumble, and built to deliver more than just a few drops at a time. With these critical qualities in mind, we called upon the legendary cold-holding power and rotomolded armor of the Tundra® Hard Cooler and fused it with an ultra-strong spigot to create a remarkably insulated, quick-to-pour, easy-to-clean powerhouse of a water cooler.
