The straw hat is perhaps the oldest and most popular hat ever made for men. It is because straw is such a suitable material for making hats. They literally have been crafted in every corner of the world using various plants and methods that grew wild in their region. That's why today you find mens straw hats woven from such a wide variety of plant fibers like toquilla, wheat straw or milan, toyo (made of paper), seagrass, and hemp braid.
