What Is Hexoskin Smart Shirt?
The Hexoskin Smart Shirt is a biometric compression garment developed by the Canadian health technology company Hexoskin. Unlike traditional fitness wearables strapped to your wrist, this shirt embeds textile electrodes and sensors directly into the fabric itself, allowing it to collect data far closer to the source — your chest, lungs, and heart.
The shirt connects to a small, lightweight recording device (the Hexoskin Device) that clips into a pocket on the side of the garment. This device stores and transmits data via Bluetooth to the Hexoskin app, giving you access to real-time and post-session biometric insights including heart rate, heart rate variability (HRV), breathing rate, breathing volume, and activity cadence.
Hexoskin has strong credibility in research and clinical settings — the technology has been used by NASA, the Canadian Armed Forces, and various sports science institutions. It’s now available to serious recreational athletes and fitness professionals who want data that goes well beyond what a standard fitness watch can offer. The shirt itself is machine washable (with the device removed), and is available in men’s and women’s cuts across a range of sizes.
Key Features
Medical-Grade Heart Rate and HRV Monitoring
The Hexoskin shirt uses ECG-quality electrodes woven into the chest fabric to capture heart rate data with a level of accuracy that optical wrist sensors simply cannot match during high-intensity movement. Heart rate variability data is logged beat-by-beat, giving coaches and athletes a genuine window into recovery status and autonomic nervous system function — not an algorithm’s estimate. During our testing, the correlation with a chest strap ECG monitor was consistently within 1-2 BPM across all intensities.
Respiratory Rate and Breathing Volume Tracking
This is where the Hexoskin truly differentiates itself. The shirt monitors both breathing rate (breaths per minute) and tidal volume (the amount of air moved per breath) using inductive plethysmography — the same principle used in clinical respiratory monitoring. For endurance athletes monitoring ventilatory thresholds, or anyone managing respiratory conditions, this data is genuinely valuable and almost impossible to capture with any other consumer wearable.
Activity and Movement Data
The onboard accelerometer tracks steps, cadence, and movement intensity, providing a complementary layer of activity data alongside the cardiac and respiratory metrics. It’s not a replacement for GPS-based running watches for distance and pace, but it adds meaningful context when combined with the breathing and heart rate feeds — particularly useful for interval sessions where you want to understand effort at a physiological level rather than purely a pace-based one.
Long-Duration Data Logging and API Access
The Hexoskin device can log data for extended periods, and the platform offers API access for researchers, coaches, and developers who want to pull raw data into their own systems. The Hexoskin app provides both live monitoring (via Bluetooth) and post-session analysis with clear graphs and exportable reports. This is a significant advantage for professional coaching environments and sports science programmes where bespoke analysis is required.

Who Is Hexoskin Smart Shirt Best For?
Perfect For:
- Endurance athletes (runners, cyclists, triathletes): The breathing volume and respiratory rate data adds a meaningful layer to threshold and VO2 max training that no wristwatch can replicate.
- Sports science coaches and researchers: API access and clinical-grade data make this the go-to tool for evidence-based coaching programmes and academic research.
- Military and tactical fitness professionals: Already used in operational research contexts — the durability and data depth make it well suited to high-stakes performance environments.
- Rehabilitation and physiotherapy settings: Monitoring breathing patterns and heart rate during recovery protocols is genuinely useful for clinicians working with cardiac or respiratory patients.
- Serious amateur athletes who want to train smarter: If you’ve outgrown the insights from your fitness watch and want to understand your physiology at a deeper level, the Hexoskin justifies its price for the committed user.
Not Ideal For:
- Casual gym-goers: If you’re doing three sessions a week and primarily want step counts and calorie estimates, this is significant overkill at a significant price.
- Swimmers: The shirt is not rated for water immersion — it’s designed for land-based training and should not be used in the pool.
- Budget-conscious fitness enthusiasts: A Polar H10 chest strap at a fraction of the cost will cover heart rate and HRV needs for most recreational athletes.
- Those who want GPS and smart notifications in one device: You’ll still need a running watch alongside the Hexoskin shirt — it doesn’t replace that functionality.
Our Verdict
The Hexoskin Smart Shirt is genuinely impressive — and genuinely niche. If you need accurate respiratory data alongside ECG-quality heart rate monitoring, there is no comparable consumer product. The breathing metrics alone put it in a category of its own, and the research-validated accuracy means you can trust what you’re seeing rather than wondering whether the algorithm is having an off day. The app could be more polished, and the price is a real commitment, but for coaches, researchers, and dedicated endurance athletes, this is a tool that earns its place.
For the average fitness enthusiast, a premium chest strap will do the job for far less. But for those who need what Hexoskin offers, it’s close to irreplaceable.
