Shop for the 3 Rivers
We’re proud to partner with The Merrimack Company, a locally owned business right here in our watershed, to bring you eco-conscious apparel and accessories that look good, feel great, and do good for the environment.
The Merrimack Company is built on three pillars—community, nature, and adventure—and is committed to reducing its environmental footprint every step of the way. Their products are made from organic and recycled materials, decorated by local screen printers and embroiderers, and sourced from ethical manufacturers, including right here in the USA.
And the best part? A portion of every sale goes directly toward protecting and preserving the Sudbury, Assabet, and Concord rivers and their watershed through OARS. When you shop here, you’re not just buying sustainable gear—you’re helping keep our rivers clean, healthy, and vibrant for generations to come.
