The track jacket: a “third piece” solution with a leisurely feel to it... one of the best weekend sweaters we can think of. This one is made of lightweight Escorial wool, an elevated alternative to cashmere that comes from a super-rare type of sheep originally kept by Spanish royalty. Soft and supple, with springy, coiled fibers that naturally resist wrinkling, it's sourced from the only direct descendants of the original Escorial flock, which are now bred in small pockets of Australia and New Zealand. Talk about special. Fun fact: as far as we know, we're the only American retailer making knits from Escorial yarn. Join us ahead of the curve.
