These aren't your dad's long underwear! Say goodbye to itchy wool and clammy cotton and say hello to NRS WaveLite Pants. This mid-weight polyester/spandex blend is warm, soft and wicks away moisture. Polartec® Power Stretch® fleece has a next-to-skin fit that moves with you and provides warmth, wicking and comfort. Polartec is the industry leader in performance layering fabrics. "Touch points" on the inner surface wick moisture quickly and pass it out to evaporate rapidly, keeping you dry when you play hard. Cut high in the back with an elastic waistband to keep the pants in place when you sit down. Four-way stretch for mobility and excellent shape-retaining fabric "memory". Form-fitting design allows layering without the added bulk of other mid-weight pants.
