Mount Everest Tea Thermo Mug A – 350 ml Insulated Travel Cup

A thermo mug keeps drinks at the temperature they were poured in by trapping heat or cold between two walls sealed under vacuum. The vacuum layer stops heat moving by conduction or convection, so the inner wall stays close to the drink's original temperature while the outer wall stays cool to touch.

To use the mug, fill it with a hot or cold drink up to the 350 ml mark, then screw the lid on tightly. The lid is designed to prevent spills when the mug is tipped or shaken, so it can be carried in a bag or cup holder. When the drink is ready, unscrew the lid and drink directly from the rim or through the sip opening built into the lid. After use, rinse the mug and lid with warm water and leave to dry.

The mug is made of stainless steel, chosen for its resistance to stains, odours and corrosion. The vacuum seal between the inner and outer walls is permanent and does not degrade with normal use. The lid is made of food-safe plastic with a silicone seal that keeps the vacuum effective and prevents leaks. The 350 ml capacity is sized for a single serving of tea or coffee, making it easy to carry without bulk.

The volume of 350 ml means the mug holds one standard cup of tea or coffee, so it fits under most kettles and coffee machines without overflow. The insulated construction keeps drinks hot for several hours or cold for a full day, depending on the starting temperature and the ambient conditions. The compact size fits in most car cup holders, rucksack pockets and worktop spaces, so it can be taken to work, on journeys or to outdoor events without taking up space.

Cleaning is simple: hand wash the mug and lid with warm soapy water, then rinse and dry. The stainless steel interior does not absorb flavours or bacteria, so the mug can be used for different drinks without lingering tastes. The lid should be washed after each use to keep the silicone seal clean and effective.

The Thermo Mug A is listed in the Mount Everest Tea travel accessories range.
