Rocky Mountain Tumbler
I love my Rocky Mountian Tumbler it keeps drinks cold all day the ice stays overnight! I found it to be hard to hold because of the size BUT they sell handles for them in a dozen different colors. They are the same ones that fit the Yetti cups without being overpriced.
Love my tumbler, it does keep drinks cold for about 24 hours. The only draw back is it is large and I have difficultly holding it.
I do like these. They work very well. But one problem - it is too big to fit my hands around it. Marta
