I bought these glasses to put my diet A AND W ROOTBEER WITH ICE in the glasses, because they said they don't sweat. But if you leave you glass set for awhile, these glasses get condinsation on the outside of the glass.I DON'T RECCOMMEND VTHESE GLASES, BECCAUSE THEY DO SWEAT. But these gasses a heavy in weight, they are made good, but the get condinsation, if they set for awhile.Jim in Ohio
