The whopping one gallon (3.7L) Rambler by YETI comes with hefty stainless steel handle and a MagCap and dock for the longest days in the wild Like the entire Rambler series, it's made from 18/8 steel for durability with a No Sweat design to keep your hands dry. Its double wall vacuum-insulated shape has the power to keep your water cold (or coffee hot) until the last sip. Big enough to get your daily recommended water intake in one go, or to keep everyone topped up on the job. Please note, the MagDock Cap is not intended for use with carbonated, perishable, or hot beverages.
