These vibrantly colored white warmers are acrylic with elastic to retain their shape. They are shorter than regular leg warmers and can be worn on your arms or legs depending on your personal style and needs. Our adult arm warmers are also the perfect length for use as girls leg warmers! Use them on their own, or layer with tights or stretch pants for more warmth. Warmers are 17 inches long, 91% acrylic and 9% elastic.
