Linen is a textile made from the fibers of the flax plant.
Linen is very strong and absorbent, and it dries faster than cotton. Because of these properties, linen is comfortable to wear in hot weather and is valued for use in garments. Linen textiles can be made from flax plant fiber, yarn, as well as woven and knitted. Linen also has other distinctive characteristics, such as its tendency to wrinkle. It takes significantly longer to harvest than a material like cotton, although both are natural fibers. It is also more difficult to weave than cotton.
Linen textiles appear to be some of the oldest in the world; their history goes back many thousands of years. From Wikipedia
