Most Fitbit devices are water-resistant to 50 meters. They're designed to be swimproof and stand up to even the sweatiest of workouts. See the table below and our user manuals for specifics as to whether your device is swimproof or splashproof.
Keep in mind that not all of our accessory bands should get wet, like those made of leather, metal, and woven materials. For more information about wearing your Fitbit device, see our Wear and Care page.

| Ace | Showerproof (don't swim with Ace - it's designed to survive splashes and spills) |
Water resistance may diminish over time and can be negatively impacted by any of the following:
- Dropping the device.
- Exposing the device to soaps, shampoos, conditioners, perfume, insect repellent, lotions, or sunscreen.
- Exposing the device to high-velocity water (for example, during water sports).
