Product overview
RAMBLER® BOTTLE STRAW CAP
For big sips on the go.
We simplified sipping with the Rambler® Bottle Straw Cap. Just flip it open, take a sip, and close it tight to stay moving. It’s leakproof when closed*, easy to carry (thanks to the TripleHaul™ Handle) and accommodates our wide straw, so you get more drink with every sip.
The Straw Cap is compatible with all YETI® Rambler® Bottles. Use the measurements below to cut straw according to your bottle size.
12 oz - 4 5/8"
18 oz - 6 5/8"
26 oz - 7 1/4"
36 oz - 7 7/8"
Please note: Do not use the Rambler® Bottle Straw Cap with hot or carbonated beverages or for storage of food or perishables. Learn more about product use and safety on our FAQ page. The Rambler® Bottle Straw Cap is leakproof when closed. However, if shaken or jostled when packed or placed in a bag, the straw cap may open causing contents to leak.
