The Wearable That Thinks for Your Body, Before It Breaks Down.
Mij is the world’s first heat stress sensor embedded directly into your clothing.
No straps. No charging. No friction. Just real-time protection where it matters most, under pressure.
While other wearables sit on the surface, Mij goes deeper—capturing how your body responds to heat and effort from within the shirt itself. It’s performance tech that disappears into your uniform, until you need it most.

Your Body Knows. Mij Listens.
On a rooftop. A mountain trail. A factory floor.
Wherever heat builds, it does so silently, long before your body sounds the alarm.
By the time you feel it, it's already too late.
Focus fades. Performance slips. Risk spikes.
And today, extreme heat kills more people annually than hurricanes, floods, and tornadoes combined.
Mij sees the signs your body misses.
Woven into your shirt, it monitors your body’s response to heat—before symptoms surface.
It reads the microclimate between your skin and fabric, sensing thermal strain as it builds.
When you can see what’s happening inside, everything changes:
- Sharper Focus
- Stronger Endurance
- Faster Recovery
- Deeper Sleep
- Better Health
This isn’t just performance - it’s real-time resilience, built into what you already wear.
What Makes Mij Different
These aren't features. They're why Mij changes everything you thought you knew about wearable tech.

Mij’s sensor system is embedded directly into the fabric. No wires, no straps, no daily charging stations. Just next-gen intelligence that lives in your gear and disappears into your day.

Unlike wearables that give you a single datapoint, Mij monitors thermal load across your entire body. The result? Real insight into how you're adapting — not just reacting.

With adaptive AI, Mij personalizes insights based on your movement, climate, activity, and output — helping you push harder, recover faster, and stay ahead of the curve.

Control Mij with a tap. Turn monitoring on or off anytime — no external gear required. You choose when your clothing becomes intelligent. Total privacy. Total power.
From scorching rooftops to long-haul runs, Mij is designed for brutal environments. Sweat, stretch, repeat—this isn’t lab gear. It’s made to work where you do.
Turn On Your Clothing. Be the first to know.
Your Body. In Real Time.
Mij is your personal thermal intelligence system - tracking how your body generates, stores, and releases heat, moment by moment.
Whether you're grinding through a high-intensity workout or pushing limits in an extreme environment, Mij helps you stay ahead of overheating, fatigue, and performance drop-off.
Its cutting-edge sensors are woven directly into your gear - delivering invisible, always-on feedback so you can manage stress, optimize output, and stay in control under pressure.
This isn’t just tech. It’s your edge - in motion, on demand, and built to keep up.
