Very small when folded, 30-liter storage capacity when unfolded. Made from lightweight "rip-stop" polyester. Water-resistant thanks to the polyurethane coating.
When folded, the Flexpack is no bigger than a fist, so it can easily be stored in any tank bag. When you unfold this ball, it forms a backpack with a capacity of 30 litres, large enough to fit a motorcycle helmet. This practical backpack is made of "75D rip stop" polyester with a polyurethane coating and is therefore very resistant to rain.
