SIGG Thermo Flasks
As well as offering the best current water bottles worldwide, at SIGG we have also developed a solution for your hot drinks. Our thermo flask, made of different materials and available in different sizes, will keep your drinks hot or cold for a long time. The double-walled insulated bottles ensure that your drinks will stay hot or cold for as long as possible.
For coffee and tea lovers
With our stainless steel thermo flasks, you can enjoy your hot cup of tea or coffee every morning and also later on in the day. The stainless steel thermo water bottles keep drinks hot and cold with their vacuum insulation and they are BPA-free. The 0.3 L and 0.5 L thermo flasks have a tea filter for brewing tea in your flask. The larger 0.75 L and 1.0 L bottles have a built-in cup that can be attached to the top or bottom of the flask. This means you can easily enjoy lots of tea or coffee.
State-of-the-art design with full functionality
Alongside stainless steel bottles, you can also buy stylish glass thermo bottles from SIGG. Your drinks will really stand out in this thermo bottle. The 0.4 L bottles made of double-walled borosilicate glass are unbreakable, tasteless and come with a built-in stainless steel filter. So you can prepare drinks with loose tea or fresh fruit directly in the bottle. The removable silicone sleeves ensure a firm grip on many surfaces and a comfortable feel.
Quick and easy access to your drink
We designed the Hot & Cold ONE so you can easily use our thermo flask with one hand. This thermal flask, with its lid that opens at the touch of a button, has become one of our bestsellers. A "lock button" allows you to seal the bottle securely, e.g. when transporting it in your bag. The Hot & Cold ONE also has a built-in tea filter.

Simple stainless steel look, bold colours or stylish glass. SIGG flasks for hot drinks are available in different designs, so you're sure to find the perfect one.
