This is a really well made, good looking flask, that most crucially does a great job of keeping drinks hot. I'm very pleased with it.

Stainless steel thermos flask

Love the fact that the flask is almost entirely made from stainless steel. The flask keeps liquids hot for quite some time which is wonderful for long journies. The only down side is that it does not pour tidily using the stopper option so spillage can be a problem. That said, we just unscrew the stopper entirely to pour which helps solve the problem.

Great thermos

A super beautifully engineered thermos. I have had quite a few over my 45 years working full time in the outdoors but the quality and the addition of an easy to clean one piece thermal cup exceeds every other one so far. This 1ltr model is more of a base camp or winter arctic sledging addition for me but it is surprisingly light. When the box arrived I thought it was going to turn out to be the wrong size. I don’t envisage ever buying another one now. Thank you Natural man and Klean Kanteen.
