Insulated GreenSmart lunch boxes are made from Neogreene, a material similar to the commonly used Neoprene, but without the use of chemicals. Neogreene is completely environmentally friendly due to its water-based ingredients, and making the material uses 25% less petroleum, 25% less energy, and eliminates toxins that can harm our air and water sources. The Sifaka Insulated Lunch Bag is stylish and functional at the same time. It doesnt look like a lunch box yet is perfectly designed for lunch transport. It features two compartments to keep hot and cold items separate, and the long drop handles make carrying it easy and fashionable. Available in bright Tangerine color!
