Very robust with a 900D polyester ripstop fabric, coated with polyurethane on the outside for even more solidity but also a better protection against bad weather and other meteorological hazards. Spacious and practical, it allows you to carry your stuff for several days. It can be carried either by the handles or by the backpack straps. The plus is that it won't clutter you up when you use it since it is compressible and stores in its own pocket.
