All-day comfort - thanks to ultra-soft backing and microfilament yarn

Microfilament yarn forms a flexible knit while an ultra-soft backing reduces friction against the skin and moves with the wrist. The knit stretches to accommodate movement without losing shape.

Comfort holds up during intense workouts and extended wear, helping to prevent chafing and irritation.

Quick swaps and secure fit - with Fast Link stainless steel components

Fast Link connectors use premium stainless steel to secure the band to compatible WHOOP hardware and allow tool-free removal. The mechanism is designed for repeated attachment and removal.

Changing colours or styles takes only seconds while maintaining a reliable, secure connection during activity.

On-demand ECG option - with WHOOP Life membership

ECG compatibility is activated via a WHOOP Life membership, enabling on-demand ECG readings when used with compatible WHOOP hardware. The band’s construction supports the required contact for measurements.

Users who track heart rhythm will find the ECG option useful for training and recovery insights, provided a membership is active.
