For most first-time travellers to Africa the thought of the strict luggage allowance can be quite daunting. Most safaris limit luggage to 15kg, however this can range from as little as 12kg to as much as 20kg, depending on the type of safari and transport you will be using.
Not only weight is important, but it is also the type of bag you have. Bags must be 100% squash-able i.e., rolling duffel bag style. Your bag should have no hard sides and no wheels. The reason for these requirements is that luggage space in 4WD Landcruisers is limited, and on the light aircraft the luggage pods are small and oddly shaped, so that why soft-sided luggage is a must.
Bags should be roughly +/- 30cm x 30cm x 70cm It is usually not a problem if your bag is slightly bigger, so long as it is 100% squash-able, and can fit into the vehicle or in the luggage compartment of a light aircraft.
Here are examples of some bags that are 100% soft-sided:
