Produced by an industrial medical supplier specifically for CORE, each patch is made from medically certified materials chosen to minimise skin irritation while maintaining a strong yet flexible hold. The foam backing naturally contours to your body for a barely-there feel, even during extended use. Whether you’re training, working, or sleeping, the patch stays in place so you can focus on your performance.

These single-use patches are ideal for those who prefer syncing their CORE with a smartwatch rather than a strap. Each pack includes 15 patches, providing several days of continuous use per patch, including overnight and during showers. Adhesion may be reduced during heavy sweating or intense physical exertion, so it's recommended to replace the patch once it loosens.

Please note that while the patches can tolerate brief water exposure, they are not designed for swimming. For water sports, a chest strap is recommended to maintain a secure fit.

Each adhesive patch is designed to hold your CORE device securely against your chest, enabling accurate body temperature readings without the need for a strap. The foam conforms to your skin for a seamless fit, helping to maintain close contact with minimal discomfort or movement. Built from breathable and medical-grade materials, the patches can stay in place through most day-to-day activities, providing flexibility for continuous monitoring.

Though suitable for short water exposure like showers, the adhesive performance may degrade with prolonged contact or during heavy sweating. When the patch starts to lift, simply replace it with a fresh one to maintain a secure fit.
