About the material: A sandwich of blended nylon/elastane and viscose/elastane (elastane is what makes a material stretchy). The face layer is a nylon blend that has moisture-wicking and abrasion-resistance qualities, and the inner viscose layer creates a silkiness that feels great against the skin. This material will keep you looking and feeling fresh all day.
