A cavalier and mask is a unique Treasure Trail item. Rather than being obtained directly, it is made by taking a Black cavalier and a Highwayman mask to Patchy on Mos Le'Harmless, who can sew the items together for 500 coins. Patchy will also disassemble the two items, for another 600 coins. A black cavalier can be obtained from level 3 clue scrolls, while a highwayman mask can be obtained from level 1 clue scrolls.
