Considered to be the first soft lunchbox in the market, these products were designed in the early 80’s using high-tech materials developed for the space program to provide a safe, light, durable, and efficient lunch-kit. The lunchbox have different interior layouts and color combinations for diverse markets ranging from school children and adults. A proprietary insulating system and fabric layering was developed to achieve the required stringent specifications. The soft lunchboxes have been a very successful item of the Igloo product line. Many user group workshops and human factors analysis were conducted to arrive to the final production designs.
