"I know what you did last summer...", you went to the harbor and had a nice bowl of delicious clam chowder while shielding your face from the rain with the help of the Southeaster Rain hat. The yellow PVC coated polyester is completely waterproof, so if you ever wanted to stand out in a torrential downpour, your hair won't get wet. The 5" high cotton lined round crown has 6 panels surrounded by a dimensional brim. The brim measurements are as follows: front - 3 3/4", sides - 6", and the back 7" wide. The inside earflap helps to protect your ears from the chilling winds and the chinstrap helps to secure the hat onto your head.
