To create this design we took satellite elevation data of Isle Royale 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.

The Isle Royale National Park Lines t-shirt has a beautiful design, but it runs a bit small. I still like it, but I'd recommend sizing up.
