There are four interior pockets. Two pockets are lined in Herdwyck No.10 pure wool tweed, made from the Herdwick fleece. The Herdwick has a 1,000 year heritage and a worthy reputation as Britain’s hardiest mountain sheep, however the fleece had long been considered almost worthless. Over a period of four years a small English company transformed this low value fleece into a high quality cloth: the Herdwyck No.10. The central pocket is lined in vintage sail cloth dating from the 1950s, with original stitching and markings. The final pocket is lined in Moon Mills Worsted wool, red no. 15.
