Hemp fibre comes from the cannabis sativa plant which grows densly and swiftly in poor soil to a height of 4 meters giving a yield 3 to 4 times more than most substitues (like cotton) without the need of agro-chemicals. The plants do this by capturing very high levels of carbon dioxide. It is also the most useful plant on the planet. All our Hemp fabrics are GOTS certified. Joe Komodo says... Hemp Works !
