Rastacap

The rastacap or tam is a tall (depending on the user's hair length), round, crocheted cap.

[citation needed] Other Caribbean terms for the rastacap include: rastafar (sometimes with a silent -r), toppa, toppah, and simply cap or hat.

Most commonly crocheted, the hat can also be knit, woven, sewn, or constructed in a number of other ways.

[citation needed] Examples with sun-cured palm leaves woven into the hat exist; this yields a semi-rigid design which a skilled islander can form rapidly.

It may also be worn by health and food service and heavy machinery workers with long hair, for workplace safety reasons.
