4.0 is formally tested to the international standard of IP68. IP, or Ingress Protection, is the measure of a device’s ability to resist dust and liquid.
WHOOP 4.0 Sensor
The WHOOP 4.0 sensor is IP68 dustproof and water-resistant at depths up to 10 meters (roughly 32 feet) for up to 2 hours - so you can continue to capture your data with zero interruptions.
The WHOOP 4.0 can be worn for most activities involving water such as:
- Swimming in chlorinated water
- Swimming in saltwater
- Hand washing or doing the dishes
Note: The WHOOP 4.0 cannot be used for diving or scuba diving.
Additionally, it is important to note that some substances like detergents, acids, insect repellent, acetone, nail polish remover, and sunscreen may degrade fabric over time or affect the signal quality. If you expose the WHOOP 4.0 to such substances make sure to wash it with fresh water. For more, see our 4.0: Wash & Care Instructions.
WHOOP 4.0 Battery Pack
The WHOOP 4.0 battery pack is IP68 dustproof and water-resistant at depths up to 1 meter (roughly 3.2 feet) for 2 hours.
