FIR Infused technology makes great use of infrared rays (FIR) which are waves of natural light energy totally invisible to the human eye. Human cells need an adequate dose of fir to function properly. Far infrared rays activate the water molecules in the blood thus increasing the flow of blood and oxygen in the blood stream. This fabric promotes cell repair and regeneration. The bamboo charcoal impregnated in this product greatly enhances infrared rays by penetrating deep into natural tissues of your body and gently raising their temperature in the treatment area. When FIR technology is combined with supportive compression, ventilation, and antimicrobial breathability properties (found in active rally bamboo fiber), the result is a therapeutic product with enhanced healing abilities. Bamboo fiber is a very soft, superior quality, hypoallergenic, latex-free material.

Similar to that of the human body products, Active Rally emit and absorb Firs and are designed to go deeper into the fabric and muscle from the "inside and out.
