About the manufacturer: The Mountain as a company grew from dress roots when two lifelong friends moved from new jersey to new Hampshire and began creating belts and buckles to sell. The most popular product was a buckle of a mountain on the back that became the company's calling card. When The Mountain incorporated and introduced its first t-shirt back in the early 90s. On that epic moment in history we made a very important decision to put the environment first by choosing water based inks and organic reactive dyes as the foundation of our production process. Since then, expanded and evolved into something that makes us pretty unique in our industry; and we are pretty proud of that.
