I came across Artifex Shirts via the Fantastic Bonanza blog. Artifex Shirts is anti-sweatshop, prints on organic cotton and donates portions of their sales to help out good ole Mother Earth. Specifically, $3 from every shirt sold is donated to Native Energy to offset 500 pounds of CO2 emissions. An additional $6 from the sale of the Windmill shirts is given to the Owl Feather War Bonnet Wind Farm to offset 1,000 pounds of CO2 emissions.
