Technology

The material does the work.

MIG3 is a bioceramic mineral — oxides of magnesium, silicon, alumina and other ceramic elements. The name stands for Mineral Inorgânico Goen3. It emits far infrared efficiently, in the 3 to 14.8 micron range.

The emission range

Why 3 to 14.8 microns matters.

The human body radiates heat almost entirely in the 8 to 14 micron band. MIG3 emits across 3 to 14.8 microns — so the range the material returns overlaps the range your body already produces. Hover the chart to read the values.

Inside the fiber

Not a coating. A material choice.

Invel patented a method of incorporating the minerals inside the fiber during manufacturing — not as a surface finish. The distinction is the whole point: a finish washes out, a mineral built into the fiber does not.

That is also why this is a material story, not a fashion one. Everything else follows from the fiber.

The proposed mechanism

Here's how Invel describes it — as a proposed mechanism, not a settled fact.

01

Body heat activates it

The composite is passive. Your own warmth is what switches it on.

02

Far infrared returns

The material re-emits energy as far infrared, back toward the area it covers.

03

The hypothesis

Invel's view is that this supports the body's own local microcirculation. We treat it as a hypothesis under study.

Proposed mechanism, under study. This is not a claim of a specific health outcome. Read the literature and its limits on the science page.

Honest limits

What the technology is not.

Specificity builds trust. So here is what MIG3 is not.

— It does not heat on its own. The energy is yours.
— It is not an electrical device. No battery, no wires.
— It is not a substitute for medical care.
— It is not medical compression, except where a garment is specifically built with compression — and then we tell you the level.

Durability & care

Because it's in the fiber, it stays.

A surface finish fades with washing. The mineral in an Invel garment is part of the fiber, so normal care keeps it where it belongs.

CARE, IN SHORT
· Machine wash cold, gentle
· No bleach, no fabric softener
· Line dry or tumble low
· The active mineral stays in the fiber
