Esbit Vacuum Flasks are a convenient way to enjoy a hot meal or beverage in the field, at the office, or on the move. The vacuum-sealed flask preserves heat for hours and the wide opening makes serving easy. Tests show that a flask filled with 208 degree F water in a 68 degree F environment will have temperature greater than 165 degrees F after 6 hours and greater than 140 degrees F after 12 hours. When you're ready to drink your hot coffee, hot tea, or soup, the outer lids serve as cups and you have a choice to use the screw plug with or without the push button for pouring function.
