Rothco’s Boonie Hat not only offers optimal protection from the harmful sun rays, but the added mosquito netting will provide a barrier between your face and neck from insects. Modeled after the classic military boonie hat, the fishing hat is made of lightweight and breathable 55% cotton / 45% polyester, while the mosquito netting is made of 100% polyester and can be pulled up into the boonie hat’s band when not in use. In addition, the bucket hat features 4 screened side vents to help keep your head cool in hotter climates. Tighten or loosen the boonie cap for the perfect fit with the adjustable chin strap. One size fits most with different hat sizes ranging from 7 – 7 ¾. If you love fishing, hunting, camping, and/or other outdoor activities, Rothco’s boonie hats are a must-have item to add to your outdoor gear collection.
