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.
