Not a High Impact Sports Bra
Originally posted on Under Armour
No, I don't recommend this
I love under armour but this is a disappointing purchase. The metal on the straps cuts in on the sides. The band rolls up which is annoying and uncomfortable. Feel like they were more concerned about still having a boob shape then holding the girls where theyre suppose to be to be active.

Hi, Becky! Thank you for the love, we appreciate you! However, we're really sorry this style missed the mark. The straps digging in and the band rolling up sounds extremely frustrating, especially when you’re expecting support and comfort for active wear! I'll be reaching out to you shortly, I would be more than happy to assist you with this.
Best bra especially if you have a large chest

I've been looking for a good bra for workouts, especially cardio and this is the one. I have a small rib cage and large breasts so sizing of s, m, l etc doesn't work but this bra does. It's so good I bought it in 4 different colours!!!

Best sports bra on the planet!!!

I used Chat GPT to find a sports bra, beacuse I was sick of bringing home many different kinds from stores only to find out it doesn't even fit me or no support etc etc. I'm so glad I did that cause with the help of AI I have found the best sports bra ever. Couldn't have asked for anything better. Right amount of support, easy to put it on even if I want to criss cross on the back. Very well made as well I can see using these sports bras for years to come. Thanks UA for creating an amazing product so I can enjoy any type of exercise and feel confident!!!

Disappointing
I spent a lot of time researching running bras and the reviews for this were so positive I gave it a go. The first couple of times I wore it I was inclined to agree with them. However, now I am using it for long runs and the weather is warming up, I find that it is chafing on the seam around the top of the bra (where the main part joins the vented fabric). Also, as I have small shoulders, I found that I can’t wear it racer back style as the straps rub on my collar bone (it’s ok as a normal style back). The underband is too wide and ends up folding in half during a run. Can’t afford to replace it so I am stuck with applying lots of body glide to make it wearable.

The cups are shaped which is great for under loose shirts (providing shape), and the straps are exactly the right width and strength. They can also be adjusted. The bottom strap also doesn't roll under during running!

I love this sports bra so much that I bought four of them. It gives great support during exercise and I love how you can make the straps crisscross or have a U-back.

I am naturally distrustful of "high impact" sports bras - with a 32DD bust in CrossFit, most bras just utterly fail to live up to the task. But this one is great! Everything is held in place, and I love that it's convertible. I went back and immediately bought 2 more. For reference, I got the small, D/DD size.

Such a well-made, supportive bra. I wear 36DD and do a lot of sports. This bra supports me very well.

4 Stars (from someone who hates bras)
Originally posted on Under Armour
Yes, I recommend this
I hate bras. But I can't run without one. This is the best bra I've found so far. I have narrow shoulders and rib cage but I'm a 34C. Usually either the cups fit or the band fits but not both. For this bra I measured a small A-C. I suspected that I might need the medium so I ordered both. I ended up deciding that I prefer the slightly better side boob coverage of the medium. The shaping is good, adjustability is excellent, wicking is good. I don't think I'll ever rate a bra 5 stars, but this one comes close!

High Quality Comfort & Support

Definitely an upgrade to my sports bra collection. It didn't eliminate bounce completely for me (I'm a 36D for reference), but it still offers a lot more support and comfort than my old bras. I hope they bring more of their colors back soon so I can get another!

Good quality
No, I don't recommend this
This is comfortable , but compared to my M&S zip up sport bras .. which you don’t seem to be doing any longer … it doesn’t make your bust neat & is expensive . Slight double boobing . Good but wouldn’t buy again

OK sport bra
No, I don't recommend this
Fits well, but I struggle to get the straps to lie flat at the back. The straps are long and I have ended up with the strap adjusters on top of my shoulders. Other than that it’s OK. Should have returned it really.
