True - wool is yesterday's fibre. All down through history, sheep have performed their marvelous double duty of feeding and clothing mankind. For over ten thousand years, wool's unique properties including warmth, stretch-resistance, breathability and ease of dyeing made it the fibre of choice for the very best clothing. More recently, nylon and other synthetic fibres from the petrochemical industry have become popular, principally due to their wash and wear properties. Since the 1950's however, much research has been invested into synthetic fibres, but chemists have not yet been able to match the warming and cooling properties, nor the feel of wool.
Wool continues as it has for the last ten thousand years, as the premier clothing fibre.
