Great bra. I wear mine as an everyday bra, and love the support and contour. I do find the band size runs just a little small (perhaps because it’s a sport bra). After several wearings, it’s not really an issue.

Ordered this in my regular size 36DDD and fit like a dream. The material is very soft. Makes me look forward to looking out again! Construction is very solid. I was really impressed by it.

This is the best bra in the universe! It is very sturdy, and has a back closure, and wide soft straps over the shoulders. The support is better than any other sports bra. I ordered 36DDD, and it fits perfect, others say it runs small, however I think it is the snug fit that gives you great support. Try this bra, it is simply the best.

I run marathons and do 100 mile bike rides in this bra. It is a great fit and very comfortable for endurance sports.

This bra is wonderful. I bought the first one for Tae Kwon Do but now wear these every day. It provides excellent support and is comfortable to wear. The bra shows under low neckline tops because it is cut high, but I prefer to switch shirts rather than wear another bra! My usual size is 32DDD and this was true to size.

Absolutely love this bra, wear it to the gym and then the rest of the day.

This is an awesome bra. I liked it so much, I ordered a second one. It is hard to find a sports bra that a) clasps in back b) is underwire and c) is supportive to large chests. This is it! And Zappos shipping was so fast I got it the next morning. Awesome!

I love this bra, although it does seem to break down quickly. This is my 3rd one. The underwire seems to break after 3-4 months of wearing 4 times a week either running or crossfitting. Still my favorite and I’ll keep ordering.

Love this bra! I tell all my friends to buy one…or two. A perfect fit. Very snug and comfortable. I just bought another to wear as my daily.

Very comfortable, great support (I’m 34DD), and no uni-boob issues. I wear it under street clothes, too, although as others have noted it is cut pretty high in the front. I’ve worn mine on several 6-10 mile hikes this spring and it’s been great – no chafing, rubbing, or slipping, and the wicking material kept me comfortable. I just got another in black I liked it so much. I only wish I could find a lower-cut bra this comfortable and supportive!

I’m a loyal Wacoal customer and this sports bra is perfect. Comfortable even if snug and very supportive. My only small annoyance with it is that the middle comes up fairly high, so it easily can’t be worn with lower cut tops.

This bra does fit snug. I normally wear 34C cinched up. This I have on the last rungs and am held tight, so if you want some maneuver room, up the ribcage size one. I have soft breasts that need shaping by a bra and this does a superb job – rounded, up, firm looking; no cone effect. I am disappointed that it doesn’t give extra cover over nipples, but I think the bra is worth it still. The spandex is very high grade and one can always add the extra layer (so I’ve heard – this will be the first time I try) for modesty…but again, I’m in no hurry since this holds so well. Really I think it’s impossible for a bra to be “no bounce”, but this is as close as it comes.

I have a love/hate relationship with this bra. I usually wear a 32 or 34G. I ordered this bra in a 34G and it is a smidge too tight in band and cup size. PRO: overall comfort, fit, support, and general shape under t-shirts. CON: not enough support for running/jogging, the front of the bra is way too high (forget wearing even a modest V-neck), the convertible straps cause the back hooks to slip off – they have never come out completely while I am wearing the bra, but while trying to put it on, half the time, the straps come un-hooked and it is a hassle to get them back in position. WORST: even while wearing, the strap hooks slip out 95 percent, so they are only hanging on by the very tip, which looks crazy unsightly and causes the metal strap hooks to gouge into your back. Since I only ever wear this in the traditional strap configuration, I am going to solve this problem by just sewing the straps permanently into place, but it is annoy to drop so much on a garment that fails from day one.

Thanks to Zappos’ free shipping and returns, I am able to try on bras without having to drag my children to a dressing room and listen to them ask questions about my chest loud enough for everyone to hear. That being said, I ordered the Wacoal Sport Underwire bra and the Natori Sport Underwire bra so I can compare the two. The Wacoal won hands down. The cups are made with a thicker fabric that doesn’t reveal how cold I feel. The straps are thick and wide and, dare I say it, comfy. Finally, the support provides a nice rounded profile, whereas the Natori made ‘the girls’ look a little depressed. I am returning both bras because the Wacoal does run a little bit smaller than the Natori and if I want to be able to breathe after eating Christmas cookies, my rib cage will need a little more wiggle room.

This is a great sports bra. I have had one in white for a couple of years and finally needed to add one more. I am a 34 G and use this for jogging, zumba, jumping rope, etc. Really good support. Gave it 5 stars, even for style, but come on, there is no such thing as a stylish sports bra for the very large chested. I am just grateful that it works!

Ice worn Wacoal bras for years and was sadly disappointed in this sports bra. The design is flawed and uncomfortable. The side panels are too big and press into the armpit. Further, it appears that the bra is inside out with a stiff center bar that does little to create support because of its location on the outside of the cups. The band was also too small. I normally wear a 36 G or H. Because this is purported to be a sports bra, I went up one band size. Despite this, the band was too tight. Not the best bra! The only thing it had going was the larger cup size

By far my best sports bra! I workout a lot (playing higher impact sports like tennis) . Being a little older and having nursed children back in the day, I need a super supportive sports bra that doesn’t allow any bounce. I have had others that, when they arrived, I liked almost as well as these, but with time they stretched or fell apart. I just reordered some of these because they held up, while the other styles I bought hadn’t!
I also like that these are underwire (you aren’t stuck with that uni-boob look).

This is just a new color of my favorite bra ever. It’s my everyday as well as my workout bra. Very supportive, comfortable and long-lasting. This bra contains my DDDs and keeps the motion under control.

I was hesitate to spend so much money on a bra, but decent sports bras are all in this price range on the market. After reading the comments, I decided to give it a try. I ended having four of them in nude color, and I will buy more in other color in the summer. I love this bra so much that not only for sports, I also wear it everyday.
I’m 5’2, 147lb, I normally wear 36/38 C/D, depends on the bra. Because I’m short, I can’t wear any bra without fully adjustable stripes. When the band size is 38, the strips are too far apart, they start to fall off my shoulders. I don’t have those problem with this bra. I do HIIT and dancing, this bra holds my chest in place, no bouncing or jiggling at all. It’s so comfortable that I forget I have boobs sometimes. I ordered 38C, it fits great, a little snug in cup size, but I don’t think a D cup would fit me. I wish they come in more sporty colors.

I have purchased 6 of these sports bras in the last year and half. I had to keep getting different sizes from losing weight. It fits amazing. I can run with confidence. It is so supportive. Love this bra. I would wear it all the time if it had a little padding.

Nice Bra… cups are good fit but band is much smaller then any other 36 I have owned. For me it should be snug because they will stretch out but this was way to small. I will order up a size and see how it fits.

I’ve worn this same style bra for several years, and it is my all time favorite because it is so comfortable. It holds me in place and there’s no chafing anywhere. I have some others from your company that I like also, but they’re not as comfortable for all day wear. I like them because they’re a little lower cut for some of my shirts, but the Simone Sport Underwire Bra is my go-to for all day comfort. At least for larger breasted women like me, I can’t recommend it high enough. One other thing … they last forever, it seems. I’ve got one I’ve worn for several years (that’s lots of washings), and it still fits like it was new. I never dry them in the dryer … only air dry. Great product!

I think this is the most comfortable bra I’ve ever had on, I wear it as an everyday bra not just a sports bra.

I’m always leery of buying bras online as I’m a tough customer when it comes to bras! I have rounding/slopey shoulders as I’m getting older (62) so straps always slide down, etc and I just am tired of buying bra after bra after bra to get some comfort 🙁 This is the 1st NON padded bra I’ve had in years and it’s awesome!! It gives me a very firm support without the extra bulk in front. NO sliding off my shoulders either…I’ve worn it numerous times on my long hikes and it stays in place and nothing moves around!! I’ve ordered 2 more Wacoal bras, not the same style, but if they are as good as this one is I’m sold for the rest of my life lol!!

I wore this backpacking in the Sierras for 6 days and it did not disappoint. Supportive, comfy and I did not notice the underwires, and gave me full coverage. I rinsed it in the river a couple times and it dried quickly in the sun, too. Even with a 40+ lb pack and hiking long miles each day, it didn’t dig into me and the shoulder straps stayed in place. Super happy and will buy another.
