I've tried different sports bras and last year I bought a Moving Comfort bra. It wicked somewhat but the problem I have with bra is that it seems to dig into my ribcage--even with the largest size. I live in a region that has high humidity and temps in the summer so I tried something else that I wore in the heat of the summer--Wacoal T-Back bra.

Even though it's underwire it's very comfie and it has never chaffed me. It works nicely under my bib shorts too. As a C cup, I am much cooler in this bra than other uni-boob style bras. I call it my hotter n hell bra.
