Knit with fine-gauge Supima® cotton yarn, America’s finest variety. Supima cotton fibers are famous for their long length. That means extra softness. They’re stronger, too, so they resist pilling. Bottom line: you can expect this henley to give you reliable wear and good looks for a long time to come. Wear it as a base layer or on its own.Supima is conscientiously sourced, American-grown cotton that’s farmed to minimize environmental impact. The fibers are 50% longer than standard cotton, so yarns are stronger, softer, less prone to fraying or pilling, and hold color longer.
