We took a lot of time to carefully select the best coffee tumbler we could find. This is a special cup that contains a ceramic coating to avoid metallic after tastes, a splash guard to retain heat between sips and much more. Meet the Third Wave Water double wall stainless steel tumbler:

• Holds 12 fluid ounces
• Ceramic Interior Coating - No more Metallic Taste!
• Double Wall Thermally Insulated Stainless Steel - Stays Hotter for Longer
• Integrated Splash Guard - Retains Heat Between Sips
  
• Powder Coated & Laser Etched - Beautifully Crafted & Long Lasting Design
• It actually FITS in Most Car Cup Holders!!! - A Small 2.625" Diameter (6.625" tall)
• Weighs only 9 ounces - Travels easy with you on your next walk-about...or hike through the CDT.
