The producer assured that before sale the thermos is completed with the full American-language information support.

Keeps warm

Tests showed flawless, the best among the participants of the technical tests(see. chart .


Internal surface of the bulb is smooth, with one seam, without any noticeable roughness.

Flavor and aroma of the beverage: does not change depending on the aroma of the previous beverage poured into the flask. The flask rinses out very well, no odor, not even the slightest trace.


The overall impression of the test: The body is quite light, but it lacks compactness. Of course this is due to functional features – the ability to float by the way we checked this in the bath: the thermos holds on to the water when the flask is full ! . The handle is ergonomic enough, but too smooth: no indentations to prevent slipping. An important feature is the stability of the case and not only: it can be placed horizontally with the handle upwards and will not roll or even move thanks to the two flat plates.

Cap: unlike its valve cap, this thermos has a screw cap, which can be opened in only one way. Two silicone rings on it are responsible for hermetic sealing.

Neck: outer diameter of 5 cm, but the inner diameter – much smaller, so the neck is very narrow, which promises difficulty with washing the thermos in the case of unauthorized “laying” of products in it no information about washing in the dishwasher . But there is no temptation to fill this thermos with borscht and meat that can, as we know, spoil.

Cap: plastic, screws in like clockwork. Very large: apparently the needs of fishermen are taken into account, most of whom are men. Stable
