Our pocket shopping bags are made out of lightweight, durable Ripstop. It is same fabric that is used for parachutes, and para-gliders. The fabric for para-gliders and kite-surfing is laminated to make it waterproof so as to enable the kite-surfer to get the kite airborne if it goes into the water. It is stiffer and more noisy. Both fabrics are extremely strong and durable. We have tested the bags to 12 kgs.
The pockets are made of a variety of bright and interesting poly cottons fabrics. For a touch of Africa we use Shweshwe (a typical South African print).
