Produced in Scottish mills from 100% pure wool. For the majority of tartans we use a 10oz wool – its lighter weight makes it perfect for a reversible waistcoat. Some rarer tartans may only be available in 13oz or 16oz, we will inform you if this is the case. Please write the name and version (Ancient, Modern, Hunting, Weathered etc.) of your tartan in the box. If you are unsure, please contact us.
