Whoop’s newest wearable is slightly smaller than the original brand and features a new sensor to improve accuracy. The new version (available September 27) can monitor blood oxygen levels and skin temperature for a more wholistic look at the body’s readiness for activity. Whoop has a cult-like following because of it uses your training, recovery, sleep and wellness data to provide personalized recommendations and feedback. The brand has also expanded its offering into apparel that can house the Whoop, so you can capture data without having it on your wrist.
