According to Heist, these tights are ""the planet's best fishnets, literally."" They're made using Q-Nova® yarns, which are woven from recycled post-consumption by-products that would otherwise be sent to landfill. Soft and comfortable, they have a hand-sewn waistband that sits flat against your stomach without rolling or digging in. The fine fabric is extra durable, so you won't need to worry about ladders as you pull them on.
