YETI® simplified sipping with the YETI Rambler Bottle Straw Cap. When you need some water (or whatever cold drink suits you), you have to flip it open, take a sip, and close it tight to stay moving. It's leak-resistant, easy to carry (thanks to the TripleHaul Handle), and has a wide straw opening to get more drink with every sip. Wherever the wild takes you, the YETI Straw Cap for the Rambler® Bottles makes it easy to sip without slowing down. This product is not designed for use with hot or carbonated beverages.
