Escorial wool, a cut-above alternative to cashmere, comes from a super-rare type of sheep originally kept by Spanish royalty. Soft and supple, with springy coiled fibers that naturally resist wrinkling, Escorial is remarkable for its longevity — in other words, it looks really great for a really long time. It’s currently produced by a single mill, and 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.
