M.E.S. Litterbug Tee Filson and their oil finish fabricsThere's nothing worse than a litterbug. The Midwest Exploration Society is less of an organization and more of a philosophy. An unofficial group of people who have a desire to explore and protect the natural world. Proceeds from every sale of a MES product will go to the non profit organization One Tree Planted. They are passionate about restoring forests, creating habitats for biodiversity, and making a positive social impact around the world.
