The only pattern of Italian camouflage used during World War II was called the M29 camo pattern or 1929 Telo Mimetico ('camouflage cloth') . The pattern was first introduced in 1929 and was used through the early 1990's, thus making it it the longest-used military camouflage pattern in the world. Initially the M29 camouflage material was used to make square shaped shelter halves that could be buttoned together to make a small "pup" tent. A second version had, a slit and flap in the center of the square so that in addition to being able to be used as a tent, it could be also worn as a poncho (similar to the way a M31 German zeltbahn could be worn).
