Jungmaven founder Robert Jungmann has been working with hemp textiles and natural dyes since '93. Tie dyeing and batiking with indigo, black tea, coffee, turmeric and making paper with the hemp scraps.  A keen environmentalist and conservationist, Jungmann has been a leader in the hemp movement since the early ‘90s. In 1993 he founded outdoor clothing company Manastash while attending college in Washington State. Jungmann sold Manastash in 2005 and left for Costa Rica shortly thereafter. While in Costa Rica, he started working with natural dyes, batik, tie-dye and hand painting shirts, all of which takes time and patience, and is less common in modern-day apparel manufacturing. This is where Jungmaven was born. After moving back to the USA, Jungmann began the search for a good, local production facility who could create beautiful, handmade hemp t-shirts.

In 2010, Jungmaven launched the Hemp2020 campaign to help raise awareness around the positive environmental impacts of hemp farming. The campaign’s vision is to “get everyone in a hemp t-shirt by 2020.” Hemp 2020 aims to get industrial hemp legal state by state. Its efforts are to help slow climate change by growing hundreds of thousands of acres of hemp to be used for food, homes, cars, paper, plastics, textiles, fuel and more.
