I love this! I have several Klean Kanteens (steel water bottles): the first two I bought were their 27 oz and 12 oz. At the time I also bought the 27 oz for my boyfriend and Dad. Now Klean Kanteen came out with an 18 oz, so I got that for me (and all my other female relatives

), and the 40 oz for my boyfriend. Needless to say, I think the 24 oz might be the most universally liked, although I think some women will like the 16 oz for themselves or smaller children (my boyfriend thinks the 12 oz is WAY too small -he could drink the whole thing in one sip). And it might be women buying them more

I just thought I would give some of my thought process in buying them

It is a good idea!
