The Waterproof Boonie Hat is the perfect choice when the weather can be unpredictable and is great for keeping your head dry and stopping rain dripping down your neck or getting in your eyes(or on your glasses). It is made from waterproof cotton material and the brim helps keep water off of your face and prevents it from going down your collar –really useful when you are out in the rain trying to get your rods out or walking around the lake looking for fish. An internal elastic adjustment means that it can be fitted to your head as tightly or loosely as you choose. It also comes in very useful at times of the year when the weather is changeable, as the brim does just as good a job of keeping the sun out of your eyes, and also helps to protect your face and the back of your neck from sunburn.
