Never drink from a moldy lid again. Unlike traditional lids that trap grime out of sight, our spout detaches quickly for full deep cleaning. Remove the straw, rinse all parts, or clean the lid safely on the dishwasher top rack for hygienic drinking every day.

Our premium vacuum insulation keeps ice intact for 24 hours and drinks cold for 8 hours, great for iced coffee, water and electrolyte beverages. When using carbonated drinks, vent the spout ahead of time to release pressure and stop overflow. Just open the spout to vent before sipping — simple for everyone.

Equipped with a true 100% leakproof seal, this tumbler brings confidence to commuting and office use. It resists spills amid bumps and movement, safe to place next to electronics and documents. Store upright for the best leakproof effect.

Made of tough 18/8 stainless steel with a reinforced shock-resistant base. Drops and rough handling will not compromise the vacuum insulation, delivering stable cooling for years. Our fully cleanable removable lid is a unique upgrade you rarely find on high-end competitor tumblers.

The streamlined handle-free 20oz design fits most car cup holders, office slots and gym holders. Ready for travel, camping and daily work. Secure the straw tightly to avoid leaks. Watch our images and video for usage demos. We provide a 30-day quality guarantee. Returns require unused goods in original packaging with all accessories intact.
