take one average synthetic jersey and place it in a side by side comparison test with wool. The wool jersey is both cooler in the heat, warmer in the cold, keeps you drier than synthetics and more comfortable at rest stops, minimize the sudden chill from evaporative cooling, stink less, and wool has a better natural drape than synthetic fabrics.
I think wool cycling clothes and longjohns are far superior to synthetics. There's some made down in your part of the world.
