Hemlocks in the southern Appalachians are under attack from a non-native insect, the hemlock wooly adelgid. If nothing is done, we will lose these magnificent trees, including the thousands of acres of old-growth in the Smokies. Will the hemlock go the way of the American chestnut and Fraser fir? Not on our watch! Proceeds from the sale of this product (and all GSMA products) go to help save the hemlock in the Smokies and other vital park projects. 100% cotton. Sizing is unisex.
