I have done this test.Take a Nero Comp.Drop it dry into the water.It floats.Take it and wring it out under water.Now it doesn't float.Now lift it out of the water and wave it around in the air and drop it again.It floats.Also put it on dry and dive in the water,you can feel the air trapped in the suit.
