The YETI Rambler 12oz Bottle is made of durable kitchen-grade 18/8 stainless steel and double wall vacuum insulation that has the power to keep your water cold or coffee hot until the last sip no matter where you take it. The bottle is dishwasher friendly and features a No Sweat design that prevents condensation. It’s topped with a unique, 360-drinking, 100% leak-proof HotShot Cap that lives up to its name by letting you sip from any side while locking in piping-hot temperatures.
