NRS H2Core Lightweight fabrics give you the same comfort and breathability as our Silkweight fabrics, but with more warmth and protection. Put on a piece of H2Core Lightweight apparel and you'll wonder how you lived without it. The brushed fabric is soft as your favorite flannel, yet dries quickly, wicks moisture and protects your skin from harmful rays. It's mid-weight weave is perfect for evenings, mornings and cool afternoons - on the water, in camp, or around town.
