Whoop 5.0 Superknit Obsidian Band

WHOOP 5.0 is the latest generation of WHOOP’s performance and recovery tracker. The device is designed around continuous physiological monitoring, with sensors that track heart rate, heart rate variability, skin temperature, and blood oxygen saturation. Unlike conventional wearables that push step counts or calorie estimates, WHOOP is built to provide strain, recovery, and sleep scores derived from biometric data. The fifth-generation model brings improvements in sensor accuracy and efficiency, running on Bluetooth Low Energy to minimize power usage and ensure faster syncing with smartphones.

The SuperKnit band in Obsidian is a fabric strap designed for durability and comfort. It is lightweight and breathable, allowing for uninterrupted use across training sessions, sleep, and daily activity. The strap design makes it possible to wear the device continuously, which is essential since the hardware does not feature a display. All interaction happens through the WHOOP mobile application, where the collected data is processed and displayed.

This package includes a 12-month WHOOP membership. The subscription is required to access the analytics platform, which provides detailed breakdowns of recovery, sleep quality, and training strain. Without an active membership, the hardware cannot be fully utilized, as it does not store or interpret raw data on its own. The included year of service ensures access to all features out of the box, with options to renew afterward.

WHOOP 5.0 is not aimed at casual users who want step counts or basic notifications. It is positioned for athletes, trainers, and individuals who want deeper physiological insights and structured feedback. The absence of a screen keeps the focus on data collection, while the companion app presents trends and recommendations in detail. The Obsidian finish keeps the design minimal, and the slim form factor ensures the band can be worn unobtrusively under clothing or gear.
