I have been jogging about 3 miles around my home every other day for about a year now but this winter I have avoid using the treadmill and opted to stay outside till it gets just too cold. So I have found that running in the cold can lead to the above mentioned malady and did some research. There are two solutions, one for women and one for men. For women all of the info says something like; since women wear a sports bra they rarely get this problem as long as it is properly sized and not made of cotton. For men they suggest several solutions; band-aids, nip guards (expensive) taping over the nipple or a lubricant (Vaseline) to protect the nipples from chafing. There is some mention of men wearing a compression top but that it would need to be quite snug to help and that it should be a material that is nipple friendly.
OK I get it, that few non-crossdressing men would read this then go and buy a sports bra to solve the problem but I'm a little disappointed that Nike, Reebok...haven't designed a top for men with a "hidden" bra like feature since this works for nearly all women. They make running tights for men, capri pants for men, the ear warmer headbands for men?
Moderator, not sure this is in the right spot but I think it is.
