Tweed is a rough, unfinished woollen fabric, of a soft, open, flexible texture, resembling cheviot or homespun, but more closely woven. It is made in either plain or twill weave and may have a check or herringbone pattern. Subdued, interesting colour effects (heather mixtures) are obtained by twisting together differently coloured woollen strands into a two- or three-ply yarn.
Tweeds are an icon of traditional British Country Clothing being desirable for informal outerwear, due to the material being moisture-resistant and durable. Tweeds are made to withstand harsh climate and are commonly worn for outdoor activities such as shooting and hunting, in both Ireland and the United Kingdom. “Lovat” is the name given to the green used in traditional Scottish tweed.
