SmartCap headwear, either caps or headbands, need to be fitted properly to ensure that they are comfortable to wear, and are obtaining the necessary signals. This means ensuring that the headwear is forward facing and centred, that there is no hair between the sweatband and forehead, and that the headwear is neither too loose nor too tight.
SmartCap should not feel tight. The best way to get the right fit is to loosen your SmartCap headwear, and wait for one minute to see if the “Cap needs adjustment” message appears. If not, continue to loosen. Incrementally loosening the cap while making sure you avoid this message ensures you will have the loosest fit possible for that style.
