All very true - which is why I like recycled pop-bottle fleeces over "virgin" fleeces for instance - but it is hard to find all the info on these things ... so I try and get kit that claims some eco-cred over thoses that ignore the issue completely.I must admit that I do not select clothing based on its environmental impact, but that being said, the environmental impact of products can be very tricky, and is not always what people expect. Some natural materials are produced at great cost, while some non-natural ones are actually relatively environmentally friendly. Some manufacturers like Patagonia for example have started to publish the details of their production chains. Hopefully more companies will do that so people can make better comparisons.
