A Boonie Hat is a wide-brimmed hat designed for outdoor activities, particularly in hot and sunny environments. It typically features a chin strap to keep it secure during windy conditions. The hat is often made from lightweight, breathable materials, making it comfortable for extended wear. Originally developed for military use, the Boonie Hat has become popular among hikers, campers, and fishermen. Its broad brim provides excellent sun protection, while ventilation holes or mesh panels help keep the wearer cool. The hat may also have loops for attaching small items, enhancing its practicality for outdoor adventures.
