mediven comfort vitality is a women's opaque graduated compression knee high built for everyday wear, combining a soft, skin-friendly knit with accurate calibrated compression. Available at 15-20 mmHg light support, 20-30 mmHg and 30-40 mmHg, the range covers everything from tired, aching legs at the end of the day through prescribed therapeutic compression. Clima Comfort™ and Clima Fresh™ keep legs cool, dry and fresh, and Acu-Knit® preserves the compression gradient over time.
