A thermos that is easy to clean, compact, and seals well.


  • stainless steel construction
  • wide mouth

I have found this be a most useful container for both cold and hot drinks. I debated whether to get the 16 or 12 oz. but was glad I went with the latter. It is the perfect size for my corresponding coffee press and is also very portable.

The main reasons I chose a Kleen Kanteen were the stailess-steel construction and the wide mouth. I wanted to get away from drinking hot liquids from a plastic container, plus the steel is easier to clean and doesn't hold the taste (which also makes it a good container for spirits).

I use it a lot as a coffee cup, so it does get stained. But every once in awhile I give it a bleach treatment and it looks good as new. The wide mouth also allows for a good scrubbing with a sponge.

I purchased the sippy-lid to go along with this but it has too small of an opening, in my opinion. But be careful of drinking hot liquids directly from the rim, as the steel does heat up. Most often I use the cap that it came with since it seals tight. It is somewhat easy to cross thread the cap, though.

With the cap in place, hot liquids stay that way for hours. If you are worried about liquids coming in contact with the plastic in the lid, well KK has thought of that detail too. The inside of the lid is stainless steel and I haven't seen any other products like that. 

Because of the material, insulation and the lid, this container is heavier than most. That is the main reason I went with the smaller size. It is also easy to dent, which hasn't yet affected the performance at least. The diameter allows for it to be jammed in MOST cupholders...unfortunately it's a very tight squeeze in my car's cupholder.

In summary, a very quality product and makes a great gift for the holidays.
