Is WHOOP Waterproof?
Is WHOOP Waterproof?
Yes, WHOOP Is Waterproof
Both WHOOP 5.0 (the current model, released May 2025) and WHOOP 4.0 are waterproof. You can wear either through swimming, showering, bathing, and heavy rain. WHOOP designs its devices to be worn 24/7, which means they handle everything your body goes through, including water.
The sensor itself is the waterproof component. The battery pack (which snaps onto the strap for charging) is not rated for submersion, but the strap and sensor are built to handle continuous water exposure.
WHOOP Water Resistance Rating
WHOOP 5.0 (Current Model)
WHOOP 5.0, released in May 2025, is waterproof and built for the same 24/7 aquatic wear as WHOOP 4.0. It adds onboard GPS and an electrocardiogram (EKG) sensor for heart health monitoring. For the current official waterproof depth specification, see whoop.com.
WHOOP 4.0
WHOOP 4.0 carries an IP68 rating, which is the highest standard consumer waterproofing rating. IP68 means the device is protected against dust and sustained submersion in water at a specified depth. WHOOP rates the 4.0 for submersion up to 10 meters.
In practical terms, both WHOOP models handle:
Pool swimming (lap swimming, recreational swimming)
Open water swimming (ocean, lake)
Showering and bathing
Water polo and aqua aerobics
Heavy rain and outdoor activities in wet conditions
Surfing and paddleboarding (surface water sports)
What WHOOP Cannot Handle in Water
IP68 to 10 meters doesn't mean unlimited waterproofing. There are situations where you should be cautious:
Scuba diving: Recreational scuba diving regularly goes below 10 meters. WHOOP is not rated for scuba and could be damaged at deeper depths.
High-pressure water jets: The IP rating doesn't cover high-velocity water like jet washes or high-pressure hoses. These can force water into seals that withstand static submersion.
Hot tubs and saunas: High temperatures and repeated thermal cycling can degrade the seals over time, though occasional hot tub use is unlikely to cause immediate damage.
Battery pack: The removable battery pack that snaps onto the strap for on-the-go charging is not waterproof. Remove it before swimming or showering.
Can You Swim with WHOOP?
Yes. Both WHOOP 5.0 and 4.0 are designed for swimming. The waterproof rating covers pool laps, open water, and ocean swimming without issue.
The HydroSleeve
WHOOP offers an optional accessory called the HydroSleeve: a clear band that fits over the WHOOP strap. It serves two purposes: it improves heart rate accuracy during swimming by keeping the sensor in firm contact with your skin (water movement can otherwise shift the strap and degrade optical HR readings), and it allows the battery pack to stay connected during swims for continuous wear.
If you swim regularly, the HydroSleeve is worth having. Without it, WHOOP can still track the duration and general heart rate profile of your swim, but accuracy tends to be lower than in dry conditions.
Does WHOOP Track Swimming Workouts?
Yes. WHOOP can auto-detect swimming as an activity and will log it as a Strain event. Swim detection has improved with software updates. You can also manually log a swim if auto-detection misses it. WHOOP tracks overall movement but uses different metrics than step-based wearables since it's optimized for cardiovascular and recovery data rather than step counting.
Heart rate accuracy in water is lower than on land due to the optical sensor interference from water movement. The HydroSleeve addresses this by pressing the sensor firmly against the skin. For pool swimming where HR accuracy matters (like training by heart rate zones), using the HydroSleeve is recommended.
Caring for Your WHOOP After Water Activities
A few habits that keep the water resistance seals in good condition over time:
Rinse the strap with fresh water after ocean or pool swimming. Salt and chlorine can degrade materials over extended exposure
Dry the area around the sensor contacts before reattaching the battery pack
Avoid leaving WHOOP soaking in water longer than necessary
Check the strap for cracks or wear periodically; a worn strap won't have the same water resistance as a new one
Using WHOOP Recovery Data with Lifestack
One of the best reasons to wear WHOOP around the clock (including in water) is the quality of recovery data it generates. Lifestack integrates with WHOOP to read your daily recovery score, HRV, and sleep performance, then uses that data to schedule your work and tasks around your actual daily energy state.
On a high-recovery day after a solid night of sleep, Lifestack schedules your deepest cognitive work in the morning. After an intense training session or a difficult night, it shifts demanding work and adds buffer time. This is what energy-based planning looks like in practice. Your calendar adapts to your recovery, not the other way around.
Frequently Asked Questions
Is WHOOP waterproof?
Yes. Both WHOOP 5.0 and WHOOP 4.0 are waterproof. WHOOP 4.0 carries an IP68 rating to 10 meters. You can wear either while swimming, showering, or bathing. The battery pack is not waterproof and should be removed before water activities.
Can I swim with my WHOOP?
Yes. WHOOP is designed for swimming. For better heart rate accuracy in the water, use the optional HydroSleeve accessory. After pool or ocean swimming, rinse the strap with fresh water to remove chlorine or salt.
Can WHOOP get wet?
Yes. WHOOP is built to get wet. Rain, sweat, showering, and pool swimming are all fine. The IP68 rating covers regular water exposure. The only component to keep dry is the removable battery pack: unclip it before swimming or showering.
Are WHOOP bands waterproof?
Yes. The WHOOP strap and sensor together are waterproof. The full sensor-and-strap unit handles pool water, ocean swimming, and daily showering without issue. The only non-waterproof part is the removable battery pack, which should be unclipped before water activities.
Is the WHOOP battery pack waterproof?
No. The sliding battery pack is not waterproof. Remove it before swimming or showering. The sensor and strap alone are IP68 rated. You can shower with just the strap and sensor in place.
Can WHOOP be worn in a hot tub?
WHOOP can survive occasional hot tub use, but it's not specifically rated for hot water or thermal extremes. Repeated hot tub exposure and high temperatures can degrade seals over time. For occasional use, the risk is low. For frequent hot tub use, consider leaving it on the edge.
Is WHOOP waterproof enough for surfing?
Generally yes for recreational surfing. The 10-meter water resistance rating handles the wave impacts and submersions typical in surfing. However, heavy wipeout scenarios with extreme water pressure can test the limits of consumer waterproofing ratings. Most surfers wear WHOOP without issues. See our best apps to use with WHOOP guide for more on getting the most from your device.
How does WHOOP compare to other waterproof wearables?
WHOOP 4.0's IP68 to 10 meters is comparable to the Oura Ring (100 meters) and typical Garmin sports watches (50 meters or more for swim models). Oura has a higher depth rating, and Garmin swim watches are rated for more intensive aquatic use. For general swimming and showering, WHOOP's rating is more than sufficient. See the full wearable comparison for more detail.
