It all starts with

Frequently Asked Questions

Sitting at the heart of Prevayl, SmartWear™ is the world’s smartest fitness tracker fused into premium sportswear. It reads your body during workout to give you real-time performance data, empowering you to adapt your training for bigger, better results. 

SmartWear™ is a three-part approach to a smarter workout. Every ① SmartWear™ garment is augmented with a smart underband and a hidden pocket – slip in the revolutionary ② Prevayl Sensor and watch your performance data come to life in the ③ Prevayl App. 

Performance Wear is our range of premium sportswear consisting of men's and women's styles, designed to complement SmartWear™ and complete the Prevayl look. 

Most fitness tracker users are using multiple devices and apps, which doesn’t make for the most effective approach. Having your data stored in endless combinations of trackers, apps and watches can often leave potential insight and performance progression untapped, too. 

Prevayl is connected clothing that you can effortlessly integrate into your workout wardrobe and fitness routine. By melding cutting-edge technology with premium sportswear, we’ve created a centralised solution which consolidates all the data captured by the Prevayl Sensor and delivers it through a slick and simplistic UI, painting a complete picture of your fitness and performance.

Prevayl negates the need for having multiple devices and apps, freeing up your wrist and storage on your smartphone. It’s the only fitness tracker and app you will ever need to take your fitness to the next level. 

Prevayl captures your performance data by measuring the electrical activity of your heart (ECG) directly in your chest cavity. This is considerably more accurate even during intense activity than any smartwatch, which uses a flashing green light to measure your heart rate from your wrist. 

Not to mention that at 1,000 data points per second, Prevayl processes four times more data than any other wearables out there, quadrupling the amount of insights into how your body performs during a workout. 

Put simply, no other wearables – let alone smartwatches – give you more performance data than Prevayl. 

Prevayl is a three-part approach to a smarter workout. Everyone new to Prevayl starts with a Training Pack, which gives you ① a revolutionary Prevayl Sensor, ② a piece of SmartWear™ garment of your choice and ③ a lifetime Prevayl App membership – everything you need to kickstart your Prevayl journey. 

The Sensor is a one-time purchase which fits into every item in our SmartWear™ collection, and a Training Pack is the first step to building your own connected workout wardrobe. 

We offer a 100-day money back guarantee for all SmartWear™ purchases and a 365-day money back guarantee for the Prevayl Sensor.

SmartWear™ is currently compatible with outdoor and indoor cycle, mountain biking, outdoor and indoor run, interval training, lifting, HIIT, walking, hiking, yoga and Pilates, and rowing. 

We’re always working on adding more workouts to the list so keep an eye out for future updates. 

Your Prevayl Sensor is only compatible with our SmartWear™ collection. Each SmartWear™ item is engineered with a smart underband and a hidden pocket to house the Sensor, enabling you to stay connected and informed throughout your workout.

Prevayl can track your electrocardiogram (ECG), heart rate, heart rate variability (HRV), core temperature, energy expenditure (kcal), training zones, inertial measurement unit (IMU), distance, orientation of the body, and thoracic bioimpedance (BioZ). 

This list will expand as we continue to improve the App and offer more fitness insights.
