I love these mugs. There is also a 20oz. version perfect for cold drinks. The story behind them is that they used to be made by Aladdin and they put everyone's logo on them including REI and a place called Fish Eating Creek Fish Camp close to where I live. I love they way they handle and keep drinks cold for hours. Also easy dishwasher safe cleaning.

When the uniform size car cup holder came about, these big mugs fell out of favor because they would not fit. Aladdin dropped them. A couple of years later an entrepreneur who saw a continued market for them bought up the tooling and now makes them in various colors. You can locate them on Ebay under the search "Thermo Serv."

I'm pleased that someone else loves this little piece of 80s technology. I use mine every day.
