For all the packraft models we use nylon 210D. This is a modern and durable material from which the cylinders of our universal packrafts "Ivolga", "Salamandra" and "Sinitsa" are made from. To compare ultralight packrafts from third-party manufacturers are made from the fabric 70D or 50D which is three times thinner than ours. We do not save on the durability of boats and use materials in which we are sure. This means that our packraft will serve faithfully for a long time and not only for 1-2 hikes. Our packrats have been tested in numerous serious expeditions to the Putoran Plateau, Patagonia, Mongolia, the Ural Range and Siberian rough rivers.
