The term 'floppy cap' can refer to two different types of headwear: a BERET and a TAM. A BERET is a soft, round, flat-crowned hat typically made of wool, cotton, or acrylic fibers. It is usually worn by both men and women and is popular in many countries. A TAM is a type of hat that is similar to a BERET but has a slightly taller crown and is usually made of heavier materials such as felt or velvet. Both the BERET and the TAM are often referred to as floppy caps due to their soft, flexible material.
