There is no definitive answer to this question as different people have different preferences. Some people prefer to wear sports bras or other types of moisture-wicking bras in hot weather, while others find that they are more comfortable in a lighter-weight cotton bra. Ultimately, it is up to the individual to decide what type of bra is best for them in hot weather.
But based on customer reviews, we recommend considering the MIRITY Women Racerback Sports Bras for hot weather or the other 10 to choose from on our list.
