The River Crossing Bag measures 90cm x 55cm and can be rolled up to store items within. The surface of the walls are waterproof and prevents water from soaking the contents stored within.

Dimensions when the bag are rolled up may vary based on the amount of items that needs to be carried within but the bag would be 45cm height and 30cm diameter on average when rolled up. 

Optimal capacity (45cm height / 30cm diameter) = 31L
