Thermos Stainless King Vacuum-Insulated Bottle STAINLESS KING 1.2 L — double-wall stainless steel, ice grey

Thermos Stainless King Vacuum-Insulated Bottle STAINLESS KING 1.2 L in ice grey is a double-wall stainless-steel flask designed to maintain beverage temperatures for extended periods. With a 1.2-litre capacity and vacuum insulation, this bottle reduces heat transfer to keep hot drinks warm and cold drinks chilled while also offering a durable construction suitable for everyday transport and outdoor use.

Advantages

The double-wall stainless-steel body and vacuum insulation deliver reliable thermal retention for hours, reducing the need for reheating or adding ice. The robust stainless-steel construction resists dents and corrosion from regular use, and the wide neck simplifies filling, pouring and cleaning. Its neutral ice grey finish provides a practical, understated look that pairs with casual and professional settings.

Suitable for

• Commuting and workplace use where long-lasting hot or cold drinks are needed
• Outdoor activities such as hiking, camping and picnics
• Travel where a durable, refillable bottle is preferred
• Everyday home use for coffee, tea, water or other beverages

When it may not be suitable

This bottle is larger and heavier than small personal flasks, so it may not be ideal for minimal pack weight or limited storage space. It is not designed as a single-use disposable container and requires regular cleaning to maintain hygiene and performance.

Key specifications

• Capacity: 1.2 litres
• Material: Double-wall stainless steel
• Insulation type: Vacuum insulation between walls
• Colour: Ice grey
• Suitable for: Hot and cold beverages
• Design features: Wide neck for filling and cleaning; screw-on lid

How to use

Preheat or precool the bottle by filling it briefly with hot or cold water to improve temperature retention, then pour the beverage you want to store. Securely close the screw-on lid to maintain the vacuum seal. When pouring, hold the bottle steadily and use the wide neck for easy transfer. After use, rinse and periodically wash the interior and lid with warm soapy water; avoid abrasive cleaners to preserve the finish. Allow parts to dry fully before reassembling.

What to consider before purchase

• Required capacity — 1.2 litres may be larger than single-person daily bottles
• Weight and packed size — consider if you need a lighter or more compact option
• Cleaning access — wide neck supports easier cleaning by hand
• Material preference — stainless steel provides durability and does not retain flavours

Usage recommendations

For best performance, precondition the bottle with hot or cold water before adding your beverage, close the lid tightly, and avoid freezing the bottle or placing it directly on open flames. Regular cleaning of the lid and seal will help maintain hygiene and optimal insulation.
