"I have a new found respect for man-made fibres like polyester, polypropylene etc as producing those fibres is so much cleaner than natural goods, and instead of having to spend a lot of energy getting the fabric to "feel" right, you just modify the properties of the fibre by changing how its produced."

Linen and hemp are also good natural fabrics. They require less water than cotton and are quite comfortable.

Their main problem is the price as they are less mass produced than cotton.
