Well, Hemp was used by man for a very very long time, although it was hardly used for clothing due to it’s firm structure, so it was “kicked out from the game” by wool, cotton and other materials, but now technologies has been developed and pleasant to wear fabrics can be produced.
Hemp grows pretty much everywhere, so it means it can be locally produced avoiding unnecessary transport and environmental costs. It takes much less water than cotton and is naturally resistant to bugs and overgrows other plants, so no pesticides and/or herbicides are involved.
Hemp is the strongest natural fibre on the planet – at least 3 times stronger than cotton. So if you’re buying clothes made out of Hemp – you know they are durable, and are going to last!
