Herdwick caps should last a lifetime. To take good care of it a soft brush should be used to remove any loose dirt and if wet, stuff with newspaper to reshape and allow to dry naturally.
Herdwick sheep are a rare heritage breed, native to the English Lake District. Early Norse settlers kept sheep in the fells and their word 'herd-vik' means sheep pasture. Hardy enough to live in the high mountains all year, Herdwick sheep have a dense, quick-drying fleece and a unique memory of their own grazing area or 'heaf'. Herdwicks have reportedly survived for days in snowdrifts during the harshest British winters.
