• Double Walled Vacuum Insulation: We use this technology to create a space between the stainless steel walls that are void of matter. This means that outside heat or cold temperature will not transfer inside.
• 18/8 Stainless Steel: Kalmateh Thermos are made out of 18/8 food grade stainless steel which provides a robust build. The thermos are also BPA Free, rust resistant, and are easy clean by hand.
• Sweat and Burn Free: Hot liquids won’t impact the exterior of Kalmateh Thermos, which means that they will not have condensation. Your bottle will always be comfortable to hold hot or cold liquids without the "sweat."
• Leak Proof: Kalmateh technology ensures that your thermos are leak proof when closed correctly with precise pouring technology.
• Thermal Copper Lining: The exterior of the inner wall in the vacuum sealed area contains copper for added insulation. Copper is added so it reduces the transfer of temperature, adding even more insulation to your thermos.
