Pure, clean-tasting beverages at max capacity. We're bringing the new face of on-the-go beverage enjoyment to your doorstep. Featuring a double-walled, smooth-fired ceramic wall over stainless steel, this guy is 100% BPA free without the metallic taste or smell. The double-vacuum insulation keeps your beverage cold for up to 50 hours and hot for 9 hours, and the stowaway carry loop makes this go wherever you go. No leaks, no spills, no questions asked.
