Juzo Varin compression thigh highs feature a two-way stretch seamless fabric that offers the highest containment of any circular knit fabric. If you suffer from moderate to severe edema, lighter weight fabrics can cut into the tissue, causing rings and folds. Varin’s unique knit prevents this from occurring. Varin thigh highs are comfortable, extremely durable, and available with a wide variety of sizing options including 3 different lengths. 77% Polyamide, 23% Lycra. Made in USA.
