What is FIRMA energywear made of?

FIRMA energywear is made of a polyamide-based yarn that have had bioactive minerals incorporated into the matrix of the yarn itself. Previous fabrics achieved similar results using coatings and capsules embedded into the yarn, but those would wear out with washes. FIRMA’s effects will never wash out as they are part of the yarn itself, making it a great innovation in the world of shapewear & fashion.
