Thermos King Beverage Bottle

Thanks to its vacuum insulation technology, this bottle is designed to keep beverages hot or cold for up to 24 hours. Performance can vary slightly based on the starting temperature of the liquid and how often you open the lid.

At 68 ounces, this is a substantial bottle that weighs significantly more when full. It is best suited for keeping in a car, at a desk, or at a campsite rather than carrying in a backpack for daily commuting.

High-quality stainless steel is non-reactive, meaning it won't retain flavors or impart a metallic taste to your water, coffee, or tea. It is a neutral material that keeps your drinks tasting exactly as they should.

While the stainless steel construction is durable, we recommend hand-washing this bottle to preserve the vacuum seal and the exterior finish over the long term. Harsh dishwasher detergents can degrade the insulation performance over time.

It is generally not recommended to use vacuum-insulated bottles for carbonated drinks. The pressure buildup can make the lid difficult to open or cause leaks, and the carbonation can be lost quickly.
