I wear a Woolrich vest when it gets warm. Fairly light and well vented in the back. Still carry on the belt like normal, just use the vest for a cover garment.
It's like the 511 but the pockets are fewer and doesn't scream this is a gun concealment vest quite as bad.
My wife shortens up the back since I sit full time. That way it hangs like a vest should and I don't have to sit on it impeding my draw.

Cue sound of Head slap.
