Sustainability
The REI Co-op Merino 185 is one of our top wool base layer picks for sustainability. At the product level, it’s produced in a Fair Trade Certified factory and REI prefers to source wool certified to the Responsible Wool Standard, also known as RWS (although it does not specify whether this base layer has RWS wool or not). Additionally, the Merino 185 received the highest longevity rating of any wool base layer we tested.
As a company, REI has a robust trade-in and reuse program for used gear called Re/Supply. Furthermore, the company is Carbon Neutral Certified, offsetting all carbon emissions through the purchase of carbon credits. Looking ahead, REI aims to reduce its greenhouse gas emissions by 50% by 2030 and reach net zero by 2050. All told, the Merino 185 meets the majority of our sustainability criteria, ensuring it is a great choice.
Below, we break down in detail all of the Merino 185's sustainability attributes at the product and brand level, including links to in-depth articles on relevant topics. For more, see our guide to the best base layers and our review of the REI Co-op Merino 185.
