Changing Bands with the new Fast Link™ Slider

With the WHOOP 4.0’s new Fast Link™ Slider, it’s never been easier to switch out your bands. You’ll never need to thread your band again to wear a new color combination or remove the sensor to place it in your WHOOP Body apparel.



Putting on Your WHOOP 4.0 for the First Time:

Your band comes pre-threaded with new Fast Link™ sliders. The first time you put on a new band, you’ll need to ensure it is adjusted to your preferred fit. Once it’s fit to you, you’ll never need to rethread or adjust it again:

  1. Open the clasp firmly with the WHOOP logo facing you.
  2. If setting up for the first time, remove the protective film.
  3. Slide your 4.0 onto either wrist (preferably your non-dominant) and adjust the band so that it sits on your wrist about 1 inch above your wrist bone.
  4. Loosen or tighten the fit by gently pulling on the end of the band.
  5. For best accuracy, make the band tight enough so that you can’t slide a finger underneath.
