Hemp is often considered an environmental "super fibre". The hemp plant is very fast growing, producing high fibre yield per acre. Hemp can produce 250% more fibre than cotton and 600% more fibre than flax with the same amount of land. Hemp leaves the soil in excellent condition, and also builds and preserves topsoil. Hemp creates one of the most eco friendly fabrics in the world, a renewable resource that can be cultivated in as little as 100 days. Hemp's tensile strength is eight times that of cotton, hypo-allergenic and non-irritating to the skin. Like linen and cotton, hemp is a cool choice as it breathes well.
