Comfortable
Originally posted on Under Armour
Yes, I recommend this
This bra is comfortable and helps with keeping sweat from pooling. Not a fan of the small, medium, large sizes make it hard to find a proper fit. I'm an A36 and that translates into a medium. I don't understand why UA can't just use normal bra sizes would make it much easier to find the correct bra. While the band fits the cups rub up into my arm pit and I have to re-adjust, which is why I gave it 4 stars.

This bra is great. I’ve used it for running and experienced no chafing and it holds everything down.

Comfortable & Supportive

I’ve tried a handful of sports bras and this one is priced right and does the job. It’s slightly padded but not too much, wider straps provide good support and comfort for my weight lifting/cardio workouts. Very pleased!!

Great for mid impact

First time I spent real money on a sports bra. Wish I would have done it sooner. Love how high it is on the chest and thick straps. Some bounce still but not as bad as other sports bras.

I have been trying to find a supportive workout bra and I finally found it. I wear a 38D and always felt like I needed two bras on during high impact workouts. This one is very supportive and covers all the right places. Highly recommend for larger breasts.

Please never stop making this.

I've been running for over ten years, and as a runner with a larger bust, I've tried numerous bras. Kelly Roberts made a video about this bra and I tried it and I'll never buy a different running bra. This is the most supportive bra while also being so comfortable. It doesn't push them up, but it also doesn't squish them down and they are great quality. I've run multiple half marathons in these without any marks or chafing. I don't know what kind of magic is in these, but please keep making them!

Great sport bra for all ages
Originally posted on Under Armour

This sport bra is perfect for me. It has great support, doesn't make me feel like I'm squished into it and the straps can be crisscrossed if desired. I don't like sport bras that I have to put on over my head. This sports bra is similar to an regular bra with the closure in the back.

I had really high hopes that this sports bra would be the answer I have been looking for, but unfortunately its like wearing a weighted vest with the right should slipping no matter how I adjust it. Its a good idea but why so heavy fabric? I ordered a medium and now having tried it I know that a large or small would not work at all. My search continues....

I needed new bras with better support. So, I ordered one from Under Armour and fit is perfect! I have the support and the fit is great. I love that I can cross the straps to wear tanks w/o the straps showing. I’m ordering my second bra today!

Sizing Challenges, Otherwise - I'm In!
Originally posted on Under Armour
Yes, I recommend this
tl;dr: This is a GOOD bra - the construction is solid without being heavy or excessive. Sizing is a challenge. For more details: I bought this in both the gray and white, both in SM(D-DD), and the gray was a better fit. I've returned the white as the top seam would show through the t-shirt I was wearing (not on the gray, weirdly enough), and the band was uncomfortably tight. Normally, yay, but for once, too tight. I think someone firmly in the DD camp around a 30/31" band (under the bust) would love this size in this bra. For reference, I normally wear a 32D (DD depending on the bra brand). The measurement instructions for this bra were, to me, confusing. I have broad shoulders, so measuring above my bust puts me at a -1 for cupsize, which makes NO sense, and if I measure under my bust, I hit around 31/32". According to the instructions on the site, I'd be a L(A-C). Having a loose bra brand is no bueno for working out, so I ditched the instructions and guessed on the S(D-DD). That said, I will try again. I am going to purchase the M(A-C) (and L(A-C) because hey, maybe I was wrong). I think it is worth finding 'the one' in this style of bra. I can't wear racer-back sports bra's - they kill my traps. Like, need physio after a workout. I have a few workout bras styled this way that are slowly disintegrating from use - I literally need this to work.

This is, by far, the best high-impact sports bra that I have ever purchased. It’s flattering and secure, perfect for cross-training / HIIT.

For reference, I am a medium/large for tops and 34D. I ordered a size medium. This bra is extremely comfortable and does not do the uniboob thing like most sports bras. I do believe I would be able to wear this as an everyday bra if I needed to.

Flawed design
Originally posted on Under Armour
No, I don't recommend this
I really want to live this bra, it fits well and is super comfortable. Unfortunately, there seems to be a pretty significant design and/or manufacturing flaw with it. The hook for the bra strap has frayed to the point that I don’t trust the strap to hold anymore. The bra is still in great shape otherwise but I can’t wear it anymore. It’s only a few months old. I expect better quality from UA.
