The water stays warm outside for 24 hours at -16-30 degrees.
Very well keeps the coffee warm. I just don’t understand why modern caps are made so awkward. When the bottle is warm, the cap should not be opened in any way from the threads if you want the last drinks out of the thermar.
Product as described. The delivery / shipping was not very fast. The Thermos was not packed very well. The box has been abused.
Good termari. Strange and impractical handle but not that going to hurt.
Good thermos. Cap and Mug practical.
Awesome heavy-duty thermari for winter hiking. Even in severe frosts, it keeps the water hot for a really long time. A good old screw cap is practically eternal compared to modern quick-release caps. The handle mechanism is weird, but let’s still go 5 stars.
