Also called the vacuum flask, this thermos flask is built with a double silicone seal that serves to prevent a temperature leak. Enjoy that coffee or tea anytime and anywhere exactly how you poured it in.

What Thermos Flasks Are

These flasks are mainly for insulation. In short, it’s all about technology. The science of how these flasks are made is simple. There are three ways heat can travel: conduction, convection, and radiation. Ordinary thermoses do not have this kind of ability, plus, it can harm you and the container as well.

The Double Wall Thermos Flasks are built with two walls for interior protection. The double-wall design prevents heat from traveling, making your drink retain the hot temperature. The copper coating on the inner bottle prevents radiation. On the other hand, it prevents convection through the vacuum between the two walls. Lastly, the thin stainless wall stops heat from entering or leaving through conduction. The stainless steel outer covering adds to the insulation technology happening inside the thermos flask.

So if you’re in the long search for effective heat-for-the-drink containment, this is the best one we can offer you.

Large Capacity and Safe Lock

What’s essential in containing the hot temperature is containing the contents itself. We don’t want to get burns from the hot drink while riding the subway, now, would we? The Double Wall Thermos Flask has a smart-lock technology. Like the walls, its built with a double-silicone seal for a powerful lock and prevents temperature leak. The 380 mL capacity can give you 13 ounces of hot drink you can drink anywhere for up to 12 hours. It won’t easily slip as well because it has a non-slip mat underneath. If this thermos flask has so much to offer both to you and your hot drink, you can now do more knowing your ready for another caffeine intake anytime and anywhere.
