A boonie hat or booney hat, also known as giggle hat, is a form of wide-brim hat commonly used by military forces. Its design is similar to a bucket hat but with a stiffer brim.
Often a fabric tape band of ‘branch loops’ is sewn around the crown of the hat. This ‘foliage ring’ is meant to hold additional vegetation as camouflage. A strap provides stability. The crown may be vented with eyelets or small mesh panels. Snaps may also be provided with which to fix the brim in the style of an Australian bush hat.
