The Lia tights are made from 100 denier recycled, premium yarn. It is knitted in 3D for an ultimate fitting and is designed with a wide, high waistband. It is a matte finish with full coverage. Each year, two billion pairs of tights are produced, worn a few times and then discarded, helping to make the textile industry the second most polluting industry in the world. Landfills everywhere are full of poorly made and cheap non-biodegradable textiles and it' getting worse. Nylon yarn, which is currently used to produce most modern pantyhose, is created from an environmentally harmful petroleum-based manufacturing process that is not only bad for the planet, but also produces pantyhose that don't last. These harmful practices in the fashion industry are all too common. Swedish Stockings believes the world needs more innovative and environmentally conscious products to lead the way. A forerunner in sustainably produced nylon stockings, Swedish Stockings produce beautiful pantyhose from recycled yarn. Their factories engage in sustainable practices including the use of environmentally friendly dyes, post-dyeing water treatment and the use of solar power for much of the energy needed in the manufacturing process. Material: 94 % recycled ecocare polyamide, 6 % elastane.
