Never drink from a moldy lid again. Ordinary lids trap grime inside hidden gaps, but our spout detaches in seconds for full deep cleaning. Take out the straw, rinse every surface, or safely clean the lid on your dishwasher’s top rack to achieve consistent, hygienic drinking.

Engineered for commuters, our tumbler features a dependable 100% leakproof seal. It resists spills through everyday bumps, letting you place it next to your laptop and documents safely. Keep the tumbler stored upright for the best leak-resistant performance.

Advanced vacuum insulation preserves ice for 24 hours and keeps beverages 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. Just vent the spout first, then sip — no tricky operation needed.

Built rugged with premium 18/8 stainless steel and a reinforced shock-absorbing base. Impacts and accidental drops won’t damage the vacuum layer, sustaining reliable cooling for years. Best of all, our fully cleanable removable lid is a standout upgrade you cannot find on many high-end competitor tumblers.

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