The dirty, covertly contagious nickname behind a popular military style of hat, the garrison cap. The hat itself is simple in construction and is typically made of felt wool, cotton, or moleskin. More recent variants include synthetic materials like polyester. It is typically associated with apparel worn on base and is not very practical for use in the field. The name comes from the top of the cap, which, when triple-creased, resembles a vagina. To preserve the dignity of the wearer, the hat, and the branch of service while maintaining the humor of the name, many troops abbreviate the name to "C-Cap". Newer variants of the cap lack the triple crease on top, effectively eliminating the resemblance to genitalia, though it's doubtful that the hat's undignified nickname caused this change.
