Yes, to an extent. The CGM sensor is water resistant but not water proof.

You can shower and sweat with the sensor on, but swimming and keeping the sensor under water for more than 30 minutes is not recommended and may cause the device to malfunction. You should not take the sensor deeper than 3 feet.

The sensor has not been tested in salt/sea water, so it is advised to avoid or minimize exposing the device to these conditions. 

Please make sure to wear the bandage that was provide to assure to sensor does not fall off or get damaged.
