Radiology pioneer Kurt Amplatz spent his career developing a way to treat babies born with heart defects by threading a Goretex-like patch through an artery to the heart and then using it to seal a hole.
That being said, if you might play in hail and pouring rain, or on the leading edge of a hurricane, and you can afford it, I suggest you do what I do, and what a lot of PGA Tour pros do, and invest in GoreTex and invest in the Rolls Royce of rainwear, Zero Restrictions.
