Yes, microplastics are pervasive (“Welcome to the Plastocene,” HCN, 11/26/18). Here is a quote from the Patagonia ad in the same issue: “The newest addition to the Patagonia Workwear line, our Steel Forge Denim blends 92% organic cotton with 8% Dyneema®, a fiber that’s light enough to float on water but 15 times stronger than steel.” Perhaps HCN and outdoor enthusiasts should start as the article hints by encouraging Patagonia and other recreation retailers to exclude plastics.
