Upgrade your RTIC 20oz Essential Tumbler (Ceramic Lined) with the ZolJet Threaded Replacement Lid. Specifically engineered for models with internal threads, this premium screw-top cover ensures a precise fit for your favorite coffee travel mug. Made from high-impact Tritan, it is up to three times more durable than standard plastic, resisting cracks and damage from daily drops. The crystal-clear design allows you to monitor your drink level at a glance and remains transparent even after repeated dishwasher cycles. For maximum hygiene, the 90-degree twist slider is completely removable, allowing for deep cleaning and preventing residue buildup. This BPA-free lid is built to withstand temperatures up to 212°F and features a straw-friendly wide opening that fits standard 6–8 mm straws or allows for smooth direct sipping. The easy one-handed sliding mechanism helps reduce splashes while you are driving, walking, or working. By replacing just the lid, you save money and keep your trusted RTIC tumbler in daily rotation. Please verify your tumbler model before purchase, as this threaded lid is not compatible with original press-fit RTIC stainless steel tumblers. Enjoy a practical, long-lasting upgrade that combines clarity, durability, and convenience for your everyday hydration needs.
