Medi Comfort thigh highs are now available with a beaded silicone top-band. Beaded silicone is great for individuals with sensitive skin, because there is less silicone touching the skin. Medi uses the latest 3-D knitting technology and microfiber yarns, to create a luxuriously soft and comfortable stocking. Their patented Climafresh system adds an anti-microbial feature to prevent the formation of odors. Clima-Comfort technology allows for high fabric breathability, which means you stay cool. To top it all off all Comfort support hosiery can be machine washed. Do not machine dry silicone bands. Made in the USA from 80% polyamide and 20% elasthane.
