For real: a Fitbit Air sensor fitted in BRIDGE, on a WHOOP-format band.
The BRIDGE adapter
Your Fitbit Air. In a WHOOP band.
BRIDGE is a small frame that connects two formats. You keep your Google Fitbit Air sensor and can wear it in WHOOP-format bands — the ones you already own, or the ones you love.
- Remove the sensorTake your Fitbit Air sensor out of its original band.
- Fit it into BRIDGEThe sensor sits in the frame's opening, which keeps the sensors underneath in contact with your skin.
- Slide it into the bandThe assembly slides into the slot of a WHOOP-format band, just like a WHOOP sensor. You're done.
Good to know: BRIDGE works one way — Fitbit Air sensor into a WHOOP band. It can't be used to wear a WHOOP sensor in a Fitbit Air band. Sensor and band not included.
