Although the cordua nylon used in manufacturing the British Army’s bergens is pretty waterproof, it is not completely so and if the bergen was to become completely saturated, such as during a river crossing, then the water would seep into the interior and damage the items carried within. To help mitigate this, small waterproof bags are issued to allow items to be put inside them before the top is secured and it is placed inside the bergen proper.
