The Wool Wind Jacket has been designed to be a high performing jacket that disguises itself as a regular piece of your wardrobe. It is constructed from 98% worsted wool and 2% Polyester, a strong and durable fabric that has a lightweight synthetic panel concealed in the front lining to protect your core from the wind and keep you warm in nasty head winds. A mesh lining is also concealed in the back to assist temperature regulation.
