Any dust proof cases?

[K.P.]

So I work in a factory. I keep my phone in my pocket and use it regularly. I’m looking for a dirt or dust proof case other than the Lifeproof Fre. Any recommendations?

Ziploc?

I'll keep that in mind.

I'll keep that in mind.

I said that only half in jest. The phone does work from inside the bag. I’ve used them at the beach.
