I gots me own McKay hat from the postman just this week. I have to admit, mate, I was a bit worried about the "biforcated" (as Capn Jack be callin it) peak...'twas a toss up for me between the McKay and the Capt Jack style.
But once I got to hold this beaut in me hands...all me misgivins were scuttled! Tis a fine hat o' quality make and any man on the account worth callin himself a pyrate would be honored to wear one o' these hats!
Oil/wax treated tis the way to go, matey. Get one if ye can, ye'll never regret it.
