The full-leg zip design allows for added heat release, ventilation and easy on and off without removing your boots. The PRO Merino is a great choice for the hunters needing a versatile hardwearing base layer bottom that is useful in a wide range of conditions. The dual-layer knit construction positions 17.5-micron Nuyarn Merino next-to-skin with a quick drying, durable polyester eyelet outer face. The Nuyarn wicks moisture away from the skin and it passes through to the surface of the Polyester. The Polyester distributes the moisture over its surface, while the eyelet construction speeds the process and encourages airflow within the fabric. This moisture management is a mechanical process, and results is a piece that absorbs, disperses, and evaporates moisture 4x faster than pure merino or comparable weight blends. Developed in New Zealand, Nuyarn technology has revolutionized the Merino wool market.
