Yeti brought the legendary insulating power of our Rambler™ Tumblers into bottle form. It's the perfect addition to rough commutes, day hikes, or kayak sessions. This insulated water bottle has the power to keep your water cold (or coffee hot) until the last sip. Like the rest of our Rambler series, the Ramble Bottles features a No Sweat™ Design to keep your hands dry with double-wall vacuum insulation to lock in temperature. Its 18/8 stainless steel construction stands up to even the toughest of conditions.
