Why choose this product

Proven Insulation Performance

Thermos is a globally recognized leader in vacuum insulation technology. This Icon Series tumbler leverages decades of expertise to ensure your beverages stay at the desired temperature for hours. Unlike many local brands that may offer shorter retention times, this imported tumbler provides reliable performance, whether you need piping hot coffee on a cool morning or ice-cold water during a humid afternoon. The 18/8 stainless steel construction ensures purity of taste, free from metallic aftertastes often found in lower-grade materials. The Mystic Navy finish is subtle yet stylish, fitting seamlessly into any setting.

Ideal for Active Lifestyles

This tumbler is perfect for individuals who are always on the go. Its 18oz (532ml) capacity is ideal for daily commutes, office use, or travel, fitting most standard car cup holders. The leak-resistant slide lock lid offers peace of mind when carrying it in a bag, though it's best used with cold liquids when open and straw-compatible. While it excels at keeping drinks hot or cold, users sensitive to lid mechanisms might find the slide lock slightly stiff initially. For those needing a completely leak-proof seal for hot liquids in transit, a screw-top thermos bottle might be a better alternative.

How to use

Prepare the Tumbler — Before first use or after cleaning, ensure the tumbler is completely dry. For optimal temperature retention, pre-condition the tumbler by filling it with hot water for hot beverages or cold water for cold beverages for 5 minutes, then empty.
Fill and Seal — Fill the tumbler with your desired hot or cold beverage, leaving about 1 inch of space at the top. Secure the slide lock lid, ensuring it is properly aligned and closed to prevent leaks. If using a straw, open the lid to insert it.
Use and Clean — Enjoy your beverage at the desired temperature. For cleaning, place the tumbler on the top rack of your dishwasher. Hand wash the lid separately to ensure thorough cleaning and longevity of its components.
