A pro golfer was so concerned about getting his clothes dirty during a shot in his round on Friday morning — he actually unbuckled his pants and ripped his top off!!

The PG-13 moment went down at the Soudal Open in Belgium … when Louis de Jager found himself in a bit of a pickle on one of the holes.

He hit a shot that landed in some muddy water — and after considering taking a penalty stroke to get a better lie … he decided to just hack it out of the hazard and take his chances.

But, not wanting the dirty area to ruin his ‘fit, de Jager ditched his shirt … and then he striped his ball away from the stuff.

Mud did, indeed, fly everywhere after his club made contact with the ground — but it appeared he avoided almost all of it. He then went on to cover his bod in his polo once more … and finish his round.

Despite the wacky scene, de Jager actually scored well — ending his day with a 2-under 69 — good enough for 23rd place.
