Cabela's E.C.W.C.S. Thermal Zone Base Layer Bottoms -
Created as an enhanced addition to our Extreme Cold Weather Clothing System (E.C.W.C.S.) program, Thermal Zone technology provides all-around versatility for a variety of weather conditions and situations in the field. Thermal Zone utilizes all three E.C.W.C.S. fabric weights combined into one garment. The weights are strategically placed in body-mapped areas to provide the ultimate in thermal regulation. The heaviest Polar Weight is used in core and maximum-exposed areas to provide optimal heat retention for the most critical zones. The Mid Weight fabric is employed in less critical areas that still receive substantial exposure. The lightest Tech Silk Weight is located in high-heat-output areas that are prone to excessive perspiration. This Silk Weight is also along the cuff areas to minimize bunching that can cause discomfort and reduced circulation to the extremities. Thermal-regulating dual-surface Polartec® Power Dry® wicks moisture to the surface for quick-drying action. Polygiene® antimicrobial treatment keeps it fresher between washes. Flatlock seams reduce chafing. Elastic waistband. Polar Weight is 93/7 polyester/spandex; Mid Weight and Silk Weight are 100% polyester. Imported.
