i may have posted this before; but i stumbled across it again today. Sebola is a French company who design and make technical sportwear for running that is environmentally sound. They use a fabric called tencel which is a closed loop product (that means there is no nasty waste byproduct) rather than the more common bamboo which is produces lots of dirty waste. you can buy sebola products direct from their own site here http://www.sebola.fr/english
