Maxis Micro Thigh Length Compression Stockings are made from a Microfibre, a combination of polyamide and Lycra. They do not contain natural rubber, which is brittle and crumbly, forms an irregular yarn which is more difficult to work with and diminishes the appearance of a stocking. Neither do they contain cotton, which absorbs and holds moisture, contains pesticides, tends to form nodules and makes an irregular yarn that leaches colour. The fibres of which Maxis stockings are made produce a fine, regular yarn that is easy to work with. Comfort and support.
