Abstract: A traveling bottle warmer bag system for keeping contents stored in containers warm for extended periods of time. The bag has three insulated layers of material that can be warmed in a microwave and stored yet retaining heat energy. The bag includes a drawstring in order to tightly close the bag after a bottle has been placed within the innermost layer to resist heat loss. When used, it eliminates the worry of a baby's bottle, tanning lotion, or other item becomes cold while traveling.
