The thermos has a carabiner — a quick-release latch in the form of a loop with a spring lock. Thanks to it, you can easily fasten a thermos, for example, on a special loop of a backpack, or, during parking, on an awning stretch or even a tree branch. Carabiners are often found in "extreme" models, designed for long trips and difficult conditions, but they also come across in household thermoses. In some cases, this part may not be an element of the thermos itself, but a cover for it (see below).
