Sunlighten infused with CELLIANT

Boost your body's infrared.

Two infrared industry leaders and innovators paired to maximize every possible health benefit in every detail of your Sunlighten sauna experience. CELLIANT® is a mineral mix that helps convert body heat into infrared energy and is key ingredient in world class brands such as UnderArmour, DesignTex, Levi’s and more. It’s natural, heat-reactive minerals and 88 trace elements ground into a fine powder we embed into the cotton yarn we use in our sauna products. 

The perfect combination of quality plus revolutionary technology designed to make your infrared sauna experience even better.

Plush Performance

Sunlighten infused with CELLIANT is a dual-purpose fabric that provides both added physical health benefits as well as comfort, luxury and practicality. Relax while our CELLIANT-infused luxury cotton fabric works with the sauna's heat and your body's natural energy to refuel your body while you enjoy your Sunlighten sauna.


CELLIANT-powered products transform your body's heat into energizing infrared light.
