Whoop 4.0 Band

Monitor your recovery, sleep, training, and health, with personalized recommendations and coaching feedback.

‍

‍DISCOVER THE NEXT GENERATION
The all-new WHOOP 4.0 is smaller, smarter, and designed with new biometric tracking, including skin temperature, blood oxygen, and more.

WEAR IT ANY-WEAR
Comfortable enough to wear non-stop thanks to new, durable SuperKnit bands, but flexibly designed to be worn off your wrist in new WHOOP Body apparel.

WAKE UP AT THE OPTIMAL TIME
Set a haptic alarm that gently vibrates to wake you at the optimal time based on your sleep needs and cycles.

MONITOR YOUR HEALTH
A robust sensor suite allows you to monitor your key vital signs: Blood oxygen levels, skin temperature readings, and heart rate metrics.

GET MORE ACCURATE DATA
5 LEDs and 4 photodiodes capture your data more often than most wearables, providing best-in-class accuracy validated in lab studies and with third-party testing.

TRACK METRICS 24/7
Wirelessly charge your WHOOP with a waterproof* battery pack and capture data continuously—even while in the shower or washing dishes.
