Award winning flask, highly recommended by multiple reviewers. This is a wonderful, tough and efficient flask.
100% plastic-free vacuum flask using trademark Klean Kanteen technology. Sturdy, attractive and made with double-walled steel, and practically unbreakable.
This is a step up from your regular Klean Kanteen flask, as the 1 litre version keeps liquids hot for 35+ hours, and cold for nearly 100 hours (the smaller versions are similarly efficient, if not to this superlative level).
The innovative 360 degree pouring action means you just tip the flask to serve. The flask is also available in a black matt finish.
