The US Army Woodland BDU Boonie Cap in size 7 is a standard-issue piece of headgear used by United States military personnel. Originally introduced during the Vietnam War and adopted for use through the late 20th century, the Boonie cap provides protection from sun and rain. Made from a durable cotton-nylon ripstop blend, this cap features the four-color woodland camouflage pattern, designed for effective concealment in temperate forest environments. The cap’s construction includes a circular brim for shade, ventilated eyelets on the crown for increased airflow, and an adjustable chin strap for secure fit. Loops around the crown, known as branch loops, allow for the addition of extra foliage or material for further camouflage. The Boonie cap is associated with the Battle Dress Uniform (BDU) system and saw widespread use among infantry, Special Forces, and support troops. Size 7 refers to the US hat sizing standard, corresponding to a head circumference of approximately 22 inches.
