Far infrared textiles · since 1992
Your body already makes the energy. We built the fabric that gives it back.
Invel garments carry MIG3, a bioceramic mineral built into the fiber itself. Activated by your own body heat, it emits far infrared in the 3 to 14.8 micron range.
No batteries. No wires. No charging.
Developed since 1992. Manufactured in a facility certified for Good Manufacturing Practice by Brazil's national health authority. Recognized in Japan for far infrared technology.
How it works
Your heat, returned to you.
It's a passive technology. The energy is yours — the fabric only gives part of it somewhere to go.
Your body radiates heat
Every person emits infrared energy, most of it in the 8 to 14 micron band.
The mineral responds
MIG3 bioceramic, embedded inside the fiber, absorbs that heat and re-emits it as far infrared.
It goes back in
The garment returns that energy to the area it covers, for as long as you wear it.
The difference
On the fabric, or in the fiber?
Most infrared garments coat the surface. Coatings fade. Invel's patented process puts the mineral inside the fiber during manufacturing, so it stays where it belongs — wash after wash.

Five things a dropshipper can't copy.
30+ years, one technology
Not a brand that jumped on a trend. Three decades of research into a single material.
Our own GMP-certified factory
Manufactured to a health-authority standard — not outsourced sewing.
Mineral in the fiber, patented
Built into the fiber during manufacturing. Not a coating.
Recognized in Japan
Validation in the most demanding market for far infrared.
A research institute since 2008
A permanent research structure — not a one-off commissioned study.
Our story
Started in Brazil. Shaped by Japan.
In 1992 a family company began importing infrared emitters from Japan. Thirty years later, Invel makes the material, spins the fiber, and sews the garment.

We'd rather show you the research than shout at you.
Far infrared textiles have been studied in peer-reviewed literature, including work on MIG3 fabric published and indexed in PubMed. Here is what those studies looked at — and what they did not.
