Well, I used SportShield again last night on an 18-mile long run and it worked fine. No chafing in any of my tender sports

My only (very minor) complaint is that SportShield is a liquid (or at least what I got is a liquid roll-on) and the container is not leak-proof. So I have to make sure it stays upright in my gym bag. Minor price to pay for what seems to be a good product. I can't say that it's better than BodyGlide. But I will keep using it.
