This YETI Rambler 18 oz Water Bottle comes with the color-matched Flip Chug Cap for quick-access hydration on nonstop days. The magnetic C-Lock slides open for a quick flip-and-sip, then presses down and locks left for a fully leakproof, spill-proof seal. A lockable covered spout keeps dust, germs, and debris off the drinking surface, so it can be tossed into a pack's hydration holster or gym bag. Built from kitchen-grade 18/8 stainless steel, the bottle is rust and puncture resistant and double-wall vacuum insulated to keep cold drinks cold. It is cupholder compatible and dishwasher safe. This unit is finished in YETI's core Black colorway. Do not use with hot or carbonated beverages, or for storing food or perishables.
