What is Polartec Power Wool Lightweight? Lightweight Powerwool is the 'in-between' weight in the Polartec Power Wool family. It features a smooth face with a soft velour wool fleece in a grid pattern for the back. It looks very similar to Power Grid. Due to the gaps between the rows of grid, the lighter colors are a little see-through. How is Power Wool Made? Polartec's Power Wool is a bi-component knit that combines the best features of both natural and synthetic fibres, without blending - a first of its kind! By placing each distinct fibre where it can work to its highest potential (merino wool against the skin and polyester on the face), Polartec has created a fabric that is soft, odor resistant, and durable. Wool fibers offer increased base comfort by retaining insulation and breathability even when wet. Their absorbent nature pulls moisture vapor away from your skin, transferring it to the outer synthetic layer where it expands and evaporates more quickly. This mechanical wicking action allows Polartec® Power Wool™ to keep moisture in motion at all times. If you would like to compare with other fabrics suitable for long underwear and tights, we have created this Legging Fabrics Matrix.
