I remember when my wife and son's bought me a Yetti tumbler (?) for Father's Day a few years ago. I dumped my normal on the rocks martini in and, as time went on, there was no thawing. Stiff to start, stiff to finish. I no longer use my Yetti for martinis...
If this works as well as their tumblers I can see a half dozen in my future. http://yeti.com/colster/
We have two of the Ozark Trail can coolers. They are identical to the Yeti Colster but cost about $8 versus about $30 for the Yeti.
For cup holder fit in cars, boats, etc., the Ozark Trail can cooler is approximately between 3/8"-1/2 "(+/-) wider in diameter across the bottom than both the 20 oz and 30 oz O.T. tumblers (which are also identical to the Yeti 20 and 30 oz tumbler). Both the Yeti Colster and Ozark Trail can cooler could be a little bit uncomfortable for smaller hands.
Barely one degree difference between the Yeti, Ozark Trail and Thermos can coolers after 4 hours, but a big difference in price.
