Madewell x Biltmore® Wool Beret Color: Mystic Yellow (mustard) OS Condition: Used one or twice. Like New! Eric Lynes, the man currently at the helm of this almost-century-old Canadian haberdashery, might be the world's foremost aficionado on gentleman's hats. (Seriously, ask him anything.) We worked with him to create this très cool felted wool beret—and you'll only find it here at Madewell. Felted wool. Spot clean. Import.
