Batt insulation facing

For a new construction 2×6 wall (in SoCal), I’ll be using plywood sheathing, Tyvek, two layers of Jumbotex, and conventional stucco. Inside will be batt insulation then drywall/wood/paint. Question: would the best practice be to use un-faced fiberglass batt insulation (as opposed to faced)?

HI Kurt -
the facings on batts are vapor retarders. In your climate, you don't need any vapor retarder on your insulation.

But kraft facers wouldn't be a problem in SoCal.
With stucco siding it would be better to NOT use FOIL faced batts.
Thank you Dana...
That's what I thought, thank you Mr. Yost...
