Descrizione
There is a specific moment on a cold morning when a vacuum flask stops being a convenience and becomes the reason the day works. The car is iced over, the trailhead is forty minutes away, and the only hot water for a hundred kilometres is the litre you brought with you.
This flask is built for that morning. Double-wall vacuum construction in 304 food-grade stainless steel holds temperature for six to twelve hours depending on fill and ambient conditions, and the screw lid seals hard enough to survive being thrown into a rucksack sideways. The interior is polished steel rather than a coated liner, so it does not hold the taste of yesterday's coffee into today's tea.
The detail that buyers notice second is the filter. A removable stainless mesh sits below the rim, so loose leaf tea, sliced ginger or citrus peel stays in the flask instead of in your teeth. It is a small addition that turns a water bottle into something you can actually brew in, which is why the 600, 800 and 1000 millilitre sizes all carry it.
Heat is not the luxury. Heat where you need it is.

Where It Belongs
Built for commuters, hikers, night-shift workers and anyone who refuses to pay four dollars for hot water at a service station. The 600 ml size fits a bicycle bottle cage and a car cup holder; the 1000 ml size covers a full day on site or a two-person hike. Buyers who brew loose leaf tea tend to take the 800 ml, because the filter makes it a genuine travel teapot rather than a flask that happens to be hot. It is equally at home on a factory floor, in a delivery van, or on a desk next to a laptop.
Questions Buyers Ask
Q: How long does it actually keep drinks hot?
A: Six hours at near-boiling fill in cold weather, closer to twelve in mild conditions. Pre-heating the flask with boiling water for two minutes before filling adds roughly two hours.
Q: Does the filter fit all three sizes?
A: Yes. The mesh filter is the same diameter across the 600, 800 and 1000 ml bodies and seats below the rim.
Q: Can I put carbonated drinks in it?
A: We do not recommend it. Pressure builds against a sealed screw lid and can force liquid out when opened.
Q: Is it dishwasher safe?
A: The body survives a dishwasher but the coating and the seal last longer with hand washing. Wash the filter separately so tea leaf does not lodge in the mesh.
Q: Will it leak in a bag?
A: The screw lid is rated leak-proof and holds under horizontal carriage. Check that the silicone gasket is seated after each wash.
Q: Does coffee flavour carry over?
A: Less than with a coated liner, because the interior is polished 304 steel. A rinse with hot water and a pinch of bicarbonate clears residual oils.
Q: What is the difference between the sizes beyond volume?
A: Only capacity and weight. The lid, filter and body diameter are shared, so a 600 ml and a 1000 ml flask are interchangeable in use.
Q: Does the outside get hot with a hot drink?
A: No. The vacuum gap isolates the outer wall, so a flask filled with boiling water is comfortable to hold. That is also why condensation does not form on the outside in cold weather.
Q: Is the plastic in the lid safe for hot liquid?
A: The lid and filter housing use food-grade PP and silicone rated for beverage temperatures. Nothing in the liquid path is unlined aluminium.
