Big Boy Thermos 1.3 l – Black
A 1.3-liter thermos designed for conveniently carrying both hot and cold beverages during everyday use and outdoor activities. The body is made of high-quality 304 stainless steel, which ensures the durability of the construction. The exterior surface is additionally coated with a black protective layer.
Vacuum technology and a One Touch cap that minimizes heat loss
The double walls of the thermos are free of gases, and the space between them is filled with a vacuum. This design ensures excellent thermal insulation, helping to maintain the temperature of the beverage inside for a long time. At the same time, this design prevents water vapor from condensing on the outside of the thermos when there are large temperature differences. The One Touch cap allows for convenient pouring without having to unscrew it completely, so the thermos remains open for a shorter time, which minimizes cooling of the contents. The design, which is free of aluminum and harmful BPA compounds, ensures that the thermos does not affect the taste or smell of the beverages stored and transported in it.

Fold-out handle, adjustable carrying strap, and steel tea infuser
A fold-out handle on the side of the body makes it easy to carry the thermos and allows you to strap it to the rest of your gear. The set also includes an adjustable-length carrying strap, which provides an additional way to carry it. The cap, which doubles as a cup, is equipped with a handle, making it more comfortable to use when drinking. The thermos also comes with a stainless steel tea infuser, allowing you to conveniently prepare tea without needing an additional infuser.

Keeps hot beverages warm for up to 24 hours
