Speedo as underwear

[knikon]

It depends on the cotton you use. Hanes cotton underwear is anything but comfortable or breathable however I have some organic cotton shirts that are very breathable. I prefer underwear that has lots of lycra or spandex as it is supportive yet not constricting.

I am not that big on most nylon undergarments but some of it is very comfortable and much of it either breathes better or is more comfortable than cotton.
