Strange question, but do any of you find either of these irritate you? I have both makes, though seldom use thankfully, but when on long journeys or occasionally at other times I'll use one. However, I used one on recent train journey, not sure which is which as I have in container altogether, but I became very irritated down below. Only get when I wear one. Today, wore different one & was fine, I think it was maybe Elvive. Maybe I'm super sensitive.
