This double wall 18/8 stainless steel thermal tumbler has copper vacuum insulation. It's decorated in a shiny silver-tone finish with the new Full Throttle "diamond" logo. The diamond logo is repeated on opposing sides of the cup with "Sturgis, South Dakota" filling the space between on one side and a black band with a small pinstripe reading "World's Largest Biker Bar" running underneath.
The copper plating on the inner wall acts as an extra line of defense against temperature transfer. This means that heat escapes much more slowly so your hot coffee stays hot even in winter, and heat enters equally slowly so the ice in your cold drink doesn't melt even on the hottest summer day. "On average, copper vacuum insulation can make a difference of up to 9 degrees F (5 degrees C) over the course of 24 hours". This means your hot drink wil stay hot for about 8 hours and your cold drink cold for up to 16 hours.
This cup also doubles as a koozie by switching out the clear plastic threaded lid for a gasket that holds your bottle or can.
***Do not microwave!" Hand wash recommended.
