Description

Crafted from soft, stretchable nylon, the strap is both lightweight and comfortable enough for extended wear. Its one-size-fits-all design makes it highly adjustable, while its breathable material helps reduce irritation during intense use. Whether you're training indoors or out on the trails, this strap offers a secure, fuss-free alternative to disposable patches.

The CORE Chest Strap works by fastening the CORE device using the black clips provided with the unit (not included with the strap). It's fully reusable and easy to wash, making it a practical and eco-conscious choice for regular users who want a dependable way to track body temperature under varying conditions.

Please note, this product includes the strap only. It does not include a heart rate monitor or the CORE device, which must be purchased separately.

How does it work

The CORE Chest Strap ensures the sensor stays in optimal position on the torso, where core body temperature can be monitored most reliably. The close contact improves sensor accuracy by reducing movement and minimising external interference, especially important when compared to arm placement. With its secure fit and breathable material, it’s well-suited for long training sessions or all-day wear.
