We simplified sipping with the Rambler® Bottle Straw Cap. When you need some water (or whatever cold drink suits you), all you have to do is 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 so you 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. The Straw Cap is compatible with all YETI Rambler Bottles.
