American-made, eco-friendly adventure brands Nalgene Outdoor, maker of reusable water bottles, and Corbeaux Clothing, maker of eco-conscious adventure apparel, on Wednesday announced a partnership to support safe domestic drinking water.

For a limited time Nalgene will sell exclusive co-branded base layer shirts for men and women designed by Corbeaux. In turn, Nalgene Outdoor will design two limited-edition co-branded 32-ounce widemouth bottles that will be sold in Corbeaux’s flagship store in Aspen, CO, and its online store.

“We are thrilled to partner with a company as committed to sustainability and responsibility as Corbeaux Clothing; we love the brand mission and the way Corbeaux gear plays with bright, nature inspired colors just like our bottles do,” said Elissa Mcgee, general manager, Nalgene Outdoor. “The passion we have seen for the Nalgene Water Fund, from consumers and now a partner like Corbeaux, is amazing. Our shared goal for this effort is to raise the profile of, and funds to assist, those struggling with access to clean water.”
