Barbour Heritage Liddesdale Jacket. The Liddesdale has been a long time classic for Barbour and it has been successfully reintroduced this season. Constructed from a lightweight Polyamide, the outer is quilted for added warmth and detailed with traditional contrast collar panelling. Signature Barbour embroidered branding can be found at the front pocket. The Heritage style is more of a slim fitting jacket than the standard Liddesdale.
