WaterWear is a fully waterproof accessory cover for SONNET that can be used in fresh-, salt-, or chlorinated water.


Each package contains nine reusable covers and 60 single-use adhesive strips for a total of 60 uses.

Only the standard SONNET Battery Pack Cover with rechargeable, alkaline, or silver-oxide batteries can be used with WaterWear. 

If you use SONNET EAS, you must remove the EAS earhook and earmold and replace it with a SONNET earhook before using WaterWear.
