After your phone is safely secured in its iDry,
it's waterproof down to 5 metres. But that's no good if you drop your phone
in the water and it sinks to the bottom!
This floating lanyard by iDry attached to the iDry
phone case and provides sufficient buoyancy to keep your iDry and phone afloat
in case you drop it.
The floating lanyard can also be used with a wide
range of other items, including keys and underwater cameras, but please check
that it floats before letting it go!
