Yeti Rambler Tumblers Size:20oz • VenTECH™ liner prevents slippingRAMBLER TUMBLERS DETAILS Don't you hate it when your favorite beverage loses its frosty (or piping hot) goodness before you have a chance to fully enjoy it? We sure do, and that's why we over engineered our Rambler Tumblers with kitchen grade 18 8 stainless steel and double wall vacuum insulation. The result is a tough, hard wearing personal drink cooler that maintains ice twice as long as plastic tumblers and it works just as well for hot beverages.
