Far Infrared Radiation
What is FIR?
Far Infrared Radiation is a band of light energy , invisible, safe, and naturally emitted by the human body at wavelengths between 4 and 14 micrometres.
When reflected back into tissue at the correct wavelength, FIR stimulates microcirculation, accelerates cellular repair, and reduces inflammation after intense exertion.
Bio-Ceramic Infusion
Bio-ceramic particles are permanently embedded into the yarn ,not surface-coated. The technology cannot wash out or degrade.
Energy Conversion
Body heat activates the particles, which re-emit it as Far Infrared Radiation at the precise wavelength human tissue absorbs most efficiently.
Cellular Response
FIR increases local blood flow, delivering oxygen to working muscles and clearing the metabolic waste that causes soreness.
Precision Zone Mapping
We Know Where You Break Down
Lumbar spine
First site of fatigue in loaded movement
Hip flexors
Overloaded in running, cycling and strength work
Quadriceps
Primary driver — highest lactic acid accumulation
Hamstrings
Most common site of delayed onset soreness
