Swiss Brand
BPA-free & reusable
100% leak-proof. Tested.
Test winner in the major water bottle comparison
SIGG has been producing high-quality aluminum goods since 1908. Thanks to the Swiss company's rich tradition, the SIGG name today stands for quality, innovation, design, and environmental awareness. From the very beginning, the drinking bottles were designed to transport a wide variety of beverages in a leak-proof manner. This was even confirmed by Stiftung Warentest, where the sturdy SIGG bottle was the only one tested to remain completely leak-proof, making it the test winner. These outstanding features have made SIGG bottles a global synonym for intelligent, sustainable drinking bottles.
FAQs
Frequently Asked Questions
We are here for you. You can find answers to frequently asked questions in our FAQ section here. Otherwise, contact us directly via the contact form for further information.
Are SIGG bottles microwave-safe?
The bottles must not be placed in the microwave, on a hot stovetop, in a hot oven, or in the freezer.
Can hot water be put into an aluminum bottle?
Aluminium is an excellent heat conductor. This means that the temperature of the liquid inside can also be felt on the outside of the drinking bottle. We therefore recommend filling it with water at a maximum temperature of 40°C.
Which liquids can I store in SIGG water bottles?
All SIGG bottles have been tested with many different types of drinks, such as acidic drinks, carbonated drinks, milk, alcohol, apple and lemon juice, etc. However, we advise against leaving drinks with natural fermentation processes, such as apple juice or milk, in the bottle for extended periods. This natural process can promote bacterial growth and create gases and strong odors that are difficult to remove.
Are the water bottles leak-proof?
All SIGG caps are leakproof. However, caps and seals are also subject to normal wear and tear due to intensive use. We recommend not washing the bottle cap in the dishwasher, but rather removing it, rinsing it with hot water, and letting it air dry. It is often also helpful to replace the bottle seal where possible. This is available as a spare part from retailers and in our webshop.
What is the best way to clean the aluminum/glass/plastic bottles?
For aluminum bottles: Cleaning tablets or mild detergent, do not place in the dishwasher.
For glass bottles: Clean by hand only, no chlorine or bleaching agents, use soft cloths/sponges.
For plastic (e.g., Tritan, polypropylene): Although partially dishwasher-safe, hand washing with mild detergent is recommended to avoid damaging the print, etc.
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.
