Our stainless steel leak-proof insulated thermoses keep food hot or cold for hours! Pack soup or chili in the morning, and it will be steaming when you're ready to eat. Pack smoothies or yogurt, and they’ll stay cool until lunchtime. Take leftovers on-the-go to eat healthier and reduce food waste with our double-walled food jars.

Similar to a thermos, these jars maintain the temperature you start with. Pre-heat with very hot water for a few minutes before adding hot food, or pre-chill in the freezer (lid off) before adding cold food. U-Konserve insulated food jars keep pre-heated food hot for up to 5 hours and pre-chilled food cold for at least 8 hours.
