Escorial is a rare and luxurious wool from a small sheep originating from the Spanish Royal flocks of El Escorial, today only to be found in small numbers in Australia and New Zealand. The Escorial fibre is like a curled spring and when stretched throughout production processes its natural memory is to return to the original curled state. It is this characteristic that makes Escorial hats, lightweight and resilient. Lock & Co's exclusive Escorial wool felt hats come in both trilby & fedora styles. Lock's Escorial wool flat cap, with its traditional silhouette, is made from 100% Escorial wool, as is the Escorial Bakerboy cap.
