Envirosax are a great idea, and we own several. They are attractive, strong, durable bags which can fold up to a very small volumes. They are perfect as shopping bags holding up to 20 kg, and women can easily fit them in their purses. They also make great gifts. If the trend of such products picked up, possibly encouraged by taxation or interdiction of paper or plastic shopping bags, the environmental footprint of consumers would be noticeably reduced.
