Description
A good day starts with a sip that is still the right temperature. Somewhere between the kitchen and the office, between the gym floor and the steering wheel, most drinks surrender to the clock. The Oasis does not. This double-wall vacuum flask holds heat for six to twelve hours, which means the tea you pour before leaving home is still honest tea when the afternoon meeting finally lets you out.
The build is where quiet quality lives. A 316 stainless steel liner faces the liquid, chosen for its corrosion resistance and clean taste, while the outer shell and a 304 steel and PP lid handle the daily life of bags, desks and car cup holders. The integrated tea strainer separates the brew from the leaves, so flavor keeps developing at the pace you choose. A vacuum layer between the walls is what does the actual work, and it works without batteries, buttons, or attention.
There is a reason the same shape has traveled through every culture that drinks something hot: it is the most honest container there is. In 600 ml for the commute, or 800 ml for the kind of day that needs a second act, in five colors that survive the slings and arrows of an actual week, the Oasis quietly keeps its promise. Cold drinks stay cold on summer routes because the same physics run in reverse. Pour once, and let the container hold the moment until you are ready for it.
Your tea should not care what time you reach the office.

Application Scenarios
Office commuters pour a full liter-carrying 800 ml in the morning and still finish it warm at five. Gym-goers keep one in the bag with cold water that stays cold through a two-hour session. Travelers fill it at the hotel breakfast bar and hold coffee through the entire flight. Campers and road-trippers use it to keep tea brewing on long drives, while students measure study sessions in refills rather than microwaves. The handle and slim straight profile make it a natural fit for car cup holders, backpack side pockets, and the kind of absent-minded moments that end a lesser flask.
Frequently Asked Questions
Q: How long does it keep drinks hot?
The double-wall vacuum insulation holds heat for 6-12 hours depending on fill temperature and ambient conditions, and cold drinks stay cold on the same physics.
Q: Is the liner food grade?
Yes. The inner liner is made from 316 stainless steel, which is corrosion resistant and does not affect the taste of tea, coffee or water.
Q: Can I brew tea directly in the flask?
Yes. The integrated tea strainer lets you brew leaves directly in the flask and separates them when you pour, so flavor does not over-develop.
Q: Is the lid leak resistant?
The 304 stainless steel and PP lid assembly is designed for everyday carrying in bags and cup holders, with secure threading for portable use.
Q: Which size should I choose?
The 600 ml size suits commutes and desk routines, while the 800 ml size covers full days, gym sessions and travel without refills.
Q: Does it keep cold drinks cold too?
Yes. The same vacuum layer works in both directions, holding cold drinks cold for comparable durations on warm days.
Q: Is it safe to wash?
Hand washing is recommended to preserve the finish and vacuum seal; the food-grade materials are certified to CE, EU, FCM, LFGB and SGS standards.
