Is Phil Mickelson wearing a onesie at The Masters?

How much gray is too much gray?

Phil Mickelson is really challenging that question with his outfit for Friday's second round at The Masters.

The three-time champion is draped in all gray as he warms up for his 1:39 p.m tee time. He doesn't appear to be wearing a belt, begging the question if he's actually rocking a onesie?

Ryan Ballengee of GNN Radio had an interesting comparison for Mickelson's gear.

The 45-year-old sits at even par, six shots behind leader Jordan Spieth.
