Stylish, relaxing tights with graduated compression to help prevent & treat poor circulation. Flat seams & a cotton gusset make for ease of wear. The top of the tights has a control top that supports the back. We then moved down the leg to the upper thighs. Here you get between & 5/7 mm Hg compression, which is the equivalent to a light support. Moving down the leg to the knees the compression factor increases to 8/10 mm Hg which is a medium to firm support. Again supporting the knee & aiding circulation. Moving down to the ankle the compression value increases to its maxium which is 12/14 mm Hg. Here the strong compression stimulates blood flow & increases circulation. These tights are 70 denier but are not opaque. They are semi transparent & have a wealth of strength in them so you'll find them quite robust.
