Rash on my belt buckle. A rash on my stomach right next to a fist-sized belt buckle. went to dr. O, a dermatologist, and she said I'm allergic to the belt buckle and it's common in men who wear belts. She recommended applying an ointment and wearing an antiallergic belt. I bought a street belt and my rash is gone. Very happy with the Roadman and planning to buy some more belts.
