Originally only printed on shelter halves, the pattern was not intended to be worn by soldiers though the shelter halves could be used as rain-ponchoes. From 1942, the printed fabric was also used for smocks for the Italian paratroopers
At some point before the outbreak of the Second World War, the pattern was changed, possibly to accommodate printing with smaller rolls. It was scaled down and compressed slightly lengthwise, but otherwise kept the shapes and colours of the first production. The pattern varied with time, the colours becoming brighter while the print became less crisp.
