The Rambler® Flip Chug Cap gives you quick access to hydration on nonstop days. When thirst hits, switch the C-Lock to the right to unlock, and a quick flip does the trick. Then press the cap down and switch the C-Lock to the left to prevent unwanted spills. The fully leakproof cap keeps your liquids sealed as you navigate packed mornings and congested sidewalks. Thanks to a covered spout, you can toss it in your pack’s hydration holster or gym bag without worrying about the grime.

Please note: Do not use the Rambler® Flip Chug Cap with hot or carbonated beverages or for storage of food or perishables. Learn more about product use and safety on our Rambler® FAQ page.
