Amish made straw hats. These hats are woven in Amish homes with the finishing touches put on by an Amishman who then resells them to the Amish community. These are not the same hats that you find in Tourist shops. These hats were made intended for Amish use, when you see an Amish man working out in the field there is a good chance that he is wearing one of these hats.
NOTE: The size is the average diameter. To calculate your size, measure the circumference of your head, and divide by 3.14 (Pi). This will give you your size. For instance, a size 7 1/4 will fit a head that measures 22 3/4" around.
