Proper fit is essential for accurate ECG readings. Each box has one "Try Me On" garment, which you should open and try on for fit before opening the other garments. To ensure consistent and accurate data collection, the elastic band must be resting comfortably on your skin, not too tight or loose.
Note that if you open garments that don't have the "Try Me On" label, these cannot be returned.
If the "Try Me On" garment doesn't fit, refer to our Returns Page for instructions on how to return or exchange.
