The trail may be soggy, but under this wide-brimmed head cover your hair and face remains dry. Gore-TEX 3L with 100% nylon fabric is durable and waterproof/breathable for a full day in the rain. The brim has been foam-stiffened, which also allows it to float if it comes off in the water. Or you can just cinch the chin cord and hope it doesn't fall off.
