Amazon has the 6-pack Bodum Pavina 4558-10-12USW Double Wall Thermo Tumbler Glasses for $27 with free shipping. Features mouth-blown borosilicate-glass construction, 2-layer design, and is dishwasher and microwave safe.
I bought the predecessor to these, because the idea of an insulated drink holder which didn't sweat sounded good. Unfortunately they are very fragile. I just stopped using them since I only have 2 left. I was hoping the new design would solve the fragility problem, but the amazon reviews mention the same fragility, and that the new design has a hole in the bottom which allows fog to form on the inside between the layers of glass, another undesirable property.
Bought mine about five months ago...the 12-ounce version, and have not had one break yet...and we're pretty rough on them (three sons at home, youngest is 10). These are by far our favorite glasses. They have a silicone vent in the bottom that is supposed to equalize air pressure, making them less susceptible to breakage (the actual term for the issue they were having is "explosive fractures"). No fog has formed inside the glass walls thus far, and we've cleaned them repeatedly in the dishwasher. Of course, all glasses break eventually, but so far our luck has hold with these....no regrets about the purchase; I paid $32.
