This Thermos bottle has Thermos' TherMax insulation technology build in between the two Stainless Steel Walls.
It holds 1.8 liters (61 oz.) of coffee, and will keep it hot for up to 24 hours. (With a starting temperature of 203 degrees, my test show water kept inside for 12 hours, was 189 degrees; and still 176 degrees after 24 hrs.) WOW, now that's what I call real thermal retention! It has a twist and pour stopper that makes serving simple and a retractable handle that provides a steady grip for pouring. The bottle has a light and compact design with detachable shoulder strap that makes it easy to take it with you. The outside finish is brushed stainless with black hard plastic trim and it's topped off with a large cup. This NCD1800 model stands 14 1/4 inches high and has a 4 1/2 inch diameter. Comes with a 5 year warranty guarantee from Thermos.
