4.0: Wash & Care Instructions

We recommend keeping your WHOOP 4.0 clean and routinely practicing the proper maintenance and care. 

Washing and drying: 

  • Hand wash only (band and sensor). Note: While the 4.0 can be washed with the Fast Link™ Slider, do not wash the stainless steel metal portion
  • Hang to dry. 
  • Members are encouraged to also change out the slider periodically.

Note: Superknit bands are made of micro-filament yarn to maximize durability and comfort. To avoid retaining moisture, we recommend washing your Superknit regularly with soap and water (after 3-4 wears), either in the shower or off-body.
