Skin breakouts from heart rate monitor strap?

[Deanna]

I get a mild form of what you're experiencing, dry & chaffed, a little itchy. I've assumed its from either lack of ventilation or not having it on tight enough so the slight movement rubs it. I use Califlora (a homeopathic gel or cream) on it and it clears up. The gel form is easier to find and they both absorb really well so they shouldn't interfere with the performance.
