THE FIRST NATURAL SYNTHETIC-HYBRID FABRIC OF ITS KIND. Polartec® Power Wool™ is a design breakthrough for combining the distinct advantages of natural and synthetic fibers in a bi-component fabric. The industry standard of blending different yarns into a mixed composition reduces the intended benefits and hampers overall fabric performance. By isolating a merino wool interior and a synthetic fiber exterior we developed a hybrid fabric with distinct surface features to optimize wicking, breathability, odor resistance and durability. This fabric stretches 2 ways ( across the width of the roll ) it does not stretch laterally (along the length) BENEFITS Superior wicking action Fast drying Highly breathable Naturally odor resistant Shape recovery Easy care BEST USES Moisture wicking odor resistant next-to-skin base Merino wool is inherently resilient due to a cortex of intricate filaments that give the fiber its soft crimp. By adding resilient synthetic fibers in the bi-component construction we further enhance the overall tensile stability and resistance to abrasive surfaces. Polartec® Power Wool™ adapts to such divergent conditions that it can excel during a wide variety of performance activities and diverse environmental conditions. This performance ability to balance both breathability and warmth provides consistent comfort at all times. Sold by the yard we come in 1 piece
