FIRMA energywear absorbs “infrared” waves emitted by human body and re-emits the absorbed resonance as “far infrared” waves, which then penetrate the human body, promoting blood micro-circulation, vasodilation, and muscle tissue stimulation to a depth of 5cm. 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 capsulesembedded into the yarn, but those would wear out with washes. FIRMA’s effects will never wash outas they are part of the yarn itself, making it a great innovation in the world of shapewear & fashion.
