To create this design we took satellite elevation data of the island of Hawai'i (home to Hawai'i Volcanos National Park), extracted transects of that data and then ran the data through a custom-written computer script. The result is a unique representation of the national park that you will not find anywhere else. We use a high-precision printing technique to ensure that all of the fine lines are retained on the shirts and they look fantastic! All shirts are designed and printed in the USA.
