Know More. Push Further. Real-time thermal stress monitoring, built into your shirt.
Mij is a shirt that monitors heat stress — continuously, invisibly, and in real time.
It’s the first sensor-powered system woven directly into the fabric, delivering live thermal insights without the bulk, charging, or disruption of traditional wearables.
While others sit on the surface, Mij goes deeper - capturing how your body responds to heat and effort from within the shirt itself. No straps. No batteries. Just seamless data, built into what you already wear.
This is how you prevent injury. This is how you train smarter. This is how you go longer, harder, and safer - without even thinking about it.
Full Body Health + Wellness System
Before you feel it,
Mij signals it.
On a rooftop. A mountain trail. A factory floor.
Wherever heat builds, it does so silently - long before your body can warn you.
By the time you feel it, it’s already too late.
Focus fades. Performance slips. Injury risk spikes.
And extreme heat now kills more people each year than floods, hurricanes, and tornadoes combined.
Mij changes that.
Woven into your shirt, Mij monitors your body’s response to heat in real time - before symptoms surface.
It senses the microclimate between your skin and your shirt, reading thermal strain and internal stress as they build.
And when you can see what’s happening inside, everything changes:
- Sharper Focuse
- Stronger Endurance
- Faster Recovery
- Deeper Sleep
- Better Health
This isn’t just about performance. It’s about listening to the signals your body’s been sending all along.

Not a Wristband. Not a Strap. Not a Gadget.
