lightest waterproof case for iPhone 6 plus?

[ElDogman]

I'm looking for a 2nd case because occasionally I like to use the phone in the bath or hot spring. While I'm careful in the past not to drop it, I'd rather have a water proof case just incase I do.

so far I know there are

I don't think there are any waterproof cases for the 6 Plus yet. The Defender and Survivor are NOT waterproof.
