The CupCoffee insert lets you securely fit your 14, 20, or 24 oz. YETI® Rambler® and other handled mugs right into your vehicle's cup holder, so your morning brew stays put on every twisty road. A clever tapered handle opening and curved outer lip make grabbing your drink effortless, while the included StickySleeve™ and removable WeatherTech Coaster team up to boost stability and catch any rogue drips. Built with the same swappable base system as our beloved CupFone, it dials in a snug fit in virtually any cup holder—cars, RVs, boats, golf carts, you name it. Just pop it in, drop your mug, and enjoy a spill-free ride every time.
