My husband got home from commuting yesterday and was complaining of slightly raw nips. He was wearing a mountain bike jersey and it wasn't hot but the humidity is picking up. He never has this problem road riding or mountain biking because he wears bibs. When he commutes he wears baggies because the guys at the nursery (plants not babies) would never let him hear the end of it if he wore "tights".
I know a lot of marathoners wear nipple coverage. Most of my sport bras are super technical fabrics, never had any issues. Come to think of it I don't have problems with the more cottony style (although they are still moisture wicking they don't do the job as well) bras. I won't buy a sports bra that doesn't compress like crazy so maybe that is why? Men need bras, simple as that.
