Yeti is known for the extreme ice retention in their coolers, and apparently they got tired of the ice melting in their drinks! The Yeti Rambler tumblers are over-engineered for ice retention, with extra insulation in a double-walled vacuum allowing for 2-3X the temperature retention of standard plastic tumblers. They are BPA free, sweat-free, and made from 18/8 stainless steel. They fit in almost any cup holder, and are sure to give your gift-ee one less thing to complain about -- cold coffee or warm soda.
Available in two sizes -- 20oz and 30oz -- both will fit into any cup-holder.
