Cheers for that Mary. Quite interesting.
I did find this website last night when looking at it. It shows how it can be good in the warmth by keeping the skin temperature cooler and even talks about keeping warmth when it is cold.

- Linen creates a feeling of freshness in hot weather and comfort warmth in winter. It is due to high thermo insulation qualities of the linen. When the weather is hot, the temperature between the body and linen is 3-4 degree below the air. When it is cold, the linen fabric carefully saves the body’s heat.
- Linen possesses high air permeability and heat conductivity properties. Heat conductivity of linen is five times as high as that of wool and 19 times as that of silk. In hot weather those dressed in linen clothes are found to show the skin temperature 3°-4°C below that of their silk or cotton-wearing friends. According to some studies, a person wearing linen clothes perspires 1.5 times less than when dressed in cotton clothes and twice less than when dressed in viscose clothes. Meanwhile in cold weather linen is an ideal warmth-keeper;
