Opinions about the Natori Sport are fairly evenly split. The majority of users say this underwire sports bra is comfortable and supportive; one woman who has ranged between 36C and 36DDD reports that the bra has "done the job like a pro" at all breast sizes. However, some users say that although the Natori is comfortable and fine for use during low- and medium-impact pursuits, it just doesn't offer enough support for high-impact activities like jogging and horseback riding. "Still alot [sic] of bounce when I exercise," reports one, saying the bra also grows shapeless over time. We also found a couple of reports that the adjustable straps can come undone suddenly and the chest band is sometimes too tight, along with a number of comments that once you begin to sweat during exercise, the bra stays wet. Although quite a few women like the Natori Sport, both the Moving Comfort Maia (*Est. $45) and Champion Double Dry Seamless Full-Support Underwire (*Est. $40) offer underwire support and draw more favorable comments from users.
The Natori Sport bra earns brief mentions in expert reviews from Self and Women's Fitness magazines, but neither offers much analysis of the bra's performance. User reviews are more helpful, offering commentary on both positive and negative characteristics; we found hundreds of posts at HerRoom.com and FreshPair.com, and more than 30 at Amazon.com. A number of users say they purchased the Natori Sport bra because it was featured on a 2009 episode of The Doctors titled "The Breast Breakthrough."
More than 400 owners review the Natori Sport bra, giving it an average rating between 4 and 5 stars. Most like the bra and say it's very comfortable, but we found frequent reports that it's not supportive enough for high-impact exercise.
