20 oz Stainless Steel Vacuum Insulated Tumbler

Never drink from a moldy lid again. Ordinary lids trap grime inside hidden holes, but our spout detaches in seconds for a complete, deep clean. Remove the straw, rinse each surface, or safely clean the lid on the top rack of your dishwasher.

Designed for commuters, our tumbler features a 100% reliable leak-proof seal. It withstands spills through daily bumps, allowing you to place it next to your laptop and documents safely. Keep the tumbler upright for the best leak-proof performance.

Advanced vacuum insulation preserves ice for 24 hours and keeps drinks cold for 8 hours, perfect for iced coffee, water, and electrolyte drinks. When using sparkling or carbonated beverages, open the spout to release pressure and stop overflow. Simply vent the spout first, then sip—no delicate operation needed.

Built tough with premium 18/8 stainless steel and a reinforced shock-proof base. Accidental impacts and drops won't damage the vacuum layer, maintaining reliable cooling for years. Best of all, our fully cleanable detachable lid is a remarkable upgrade you can't find on many competing high-end tumblers.

This 20oz handle-free tumbler fits most standard car cup holders, desk slots, and gym racks. Effortlessly take it for commutes, camping, and work. Secure the straw tightly to prevent leaks.
