Oh, good point! Thank god you were here to stop us all from supporting these absolute monsters.
Fair-do's for meaning well, but...
If you're going to sell cycling clothing on the idea that is eco friendly because it is made in carbon neutral factories, it is fair to ask how much of the carbon cost of the product comes from delivery. I suspect that the answer is "almost all"
because sewing machines use damn all energy
As for the fair trade thing: cotton is pretty poor material for cycling gear for the UK because its cold when wet, so you're better off buying merino t shirts or various wicking ones, and you can get either from fair trade companies.
And the ultimate cycling shell is the Paramo Velez Adventure Light, which combines the advantages of hard and soft shells, is again fairtrade, and has capabilities vastly transcending those a polyester top sprayed with Nikwax.
So looked at coldly, this is a company offering products inferior to those that you can already buy from fairtrade manufacturers and the only supposed benefit - windpowered factories - means damn all. In fact, there's probably a negative ecological impact, because merino t-shirts are longer lived than cotton, so the real carbon cost - ie the one including transport - is spread over many more wears. Plus merino wool usually comes from sheep that inhabit places that can't be used to grow food crops, whereas "ecological" cotton can be a devil for replacing rice production.
But most of alll.. a cotton t-shirt costing 25 quid is just insane. If you want to help make the world, buy one for a fiver and give the other 20 to a charity. It will be a thousand times more than the fair trade contribution from 25 quid t-shirt.
