Sizing is too Broad
Originally posted on Under Armour
No, I don't recommend this
I don't know why I thought that a bra sized for A-C cups would fit me. That's a very large range for a single size. Anyway, the fit wasn't bad, but the side panels pouf out strangely from the band. It's too bad that retail stores no longer exist to try on items for fit. The bra is well-constructed with nice materials. Also, being able to adjust from the front is a brilliant design.

My measurements say I'm a medium but the bra is too tight. I'm a 36 C. I'm exchanging for a large. So if you are on the cusp of the isizes go bigger is my recommendation

Hi, Diane! We're so sorry we didn't get the sizing right on the first try. We know what an inconvenience that can be. We appreciate you giving us another shot and for calling this out. Please look for an email from me so we can further connect on this.
LOVE it, but there's one minor issue
Originally posted on Under Armour
Yes, I recommend this
These bras fit great and are really comfortable. I've gotten 3 so far, and am loving the new option with bigger cup size. My only issue is with longevity: over time, while the rest of the bra holds up, the text on the inside of the straps that's meant to prevent sliding turns to mush and slides off, exposing the adhesive.

clasp
Originally posted on Under Armour
No, I don't recommend this
I saw someone mention the shoulder clasp and how it can fall out. I should have pain attention. The first wash in a garment laundry bag and one of the shoulder clasps is gone. I can't find it. The bra is of no use to me any longer. It also has sizing issues. The cups are really large. Much larger than they should be for a sports bra.

Oh no, we hate that this happened, especially since you were careful with washing it. That is so frustrating, and we can completely understand how the fit and the clasp issue would make it a letdown. Please look out for an email from me to help get this sorted!

The best sports bra I tried out of 6+ šš» Was starting to give up hope tbh. A good-looking & supportive bra with extra wide straps to counter-act any bounce.

The back straps are horrible
Originally posted on Under Armour
No, I don't recommend this
The straps being crossed makes itās so much worse, if you even slightly adjust the straps to get more support the back of the bra where the straps loo through bunch up and get twisted in a very uncomfortable I have had this bra before this version is so bad itās so frustrating. I have always ordered this size for years so itās definitely this bra

This bra is so comfortable while supporting well. It washes great and I donāt have enough good things to say about it. The idea of having the straps adjustable in front is genius. It makes it easy to change straps while wearing. Itās awesome!

Cut too high under arms
Originally posted on Under Armour
No, I don't recommend this
Like the back closure and adjustable straps but I have never had a sports bra rub under my arms raw no matter how I adjust the shoulder straps. Wish it was cut to fit a bit better as I love everything else about it but cannot wear either now due to the discomfort of the rubbing.

So now that Iām in my 40ās I have a difficult time putting a sports bra on over my head and even more difficulty taking it off. Lol! Well, that being said this amazingly perfect having a clasp makes it so much easier getting on and off and a super comfortable. I am five 657 pounds. I typically wear a size 34C/D and I ordered a medium and it fits just right.

Excellent Sports Bra
Originally posted on Under Armour
Yes, I recommend this
This is an excellent sports bra with a superb design. Sizing is spot on according to the chart which is always nice. No removable, annoying cups, no uniboob because of the unique design of the cups, nice and breathable material, light weight. Comes higher up by the armpits when is nice, straps EASILY switch to crossover which is really great. The straps themselves seem quite heavy duty, like almost overkill unless your chest is just giant. Comfortable straps though, just intense. Love this bra and washes well.

Great quality, great bra!
Yes, I recommend this
This is a really good fitting bra and, for a sports bra, actually pretty comfortable. It feels and looks āthickā and big but once you get it on, it looks and fits great! Fabulous quality, good fabric, supportive and āengineeredā well, but it should be for the price. The adjustable interchangeable strap position is inspired and the straps detaching at the front makes it easy to get on if you have them in an X back pattern. You need to size up as Iām a āsmallā 38 C in M&S bras and not on the end hook and eye, and size Large in this bra fits me perfectly. If my back was broader, it would cut in uncomfortably. Iāll probably buy another when Iāve saved up!

Great support
Great support without having underwire. Bra fabric is more of a neoprene, which is mouded to create support for larger ladies.Very comfortable once you have sorted out yr correct size via Under Armour Website..this is why i have ordered this product via M&S.. because the returns via UA website is a nightmare compared to Marks.. I now have 2 lovely comfy bra's. My one BIG disappointment is, i made this order on my Marks website during my Sparks 20% off bra's.. then clicking on to pay it didn't include under Armour..WHY-NOT??

Fits well but smelly

On arrival, the item came in a sealed bag. I washed it, but itās still smelly. I wore it twice. Good fit. A little hard to self close. I thought this was more of a bra like band.

Thanks for taking the time to share this. Iām really sorry the bra arrived with an odor even after washing, and that the closure felt tougher to manage than expected. Iām glad the fit worked for you, but you shouldnāt have to deal with anything that feels off right from the start. Iāll follow up with you by email so we can help make this right!
Perfect support for every day wear

I really like this specific style because you can choose straight straps instead of cross back, I also like the wide straps. It is great for every day wear, not just physical activity. It is really comfortable.

Poor Design
Originally posted on Under Armour
No, I don't recommend this
Not sure who this is supposed to work for. The padding is super thick and stiff so really not comfortable in a sports bra meant for running. Its incredibly difficult to put on and offers little to no support for even me who's small chested. The band is super thick and heavy making breathing impossible and on a run thats pretty important. Someone needs to learn how to design functional sports bras again.

I bought two of these (black & white). I ordered my regular top size (medium) and the D/DD cup and it fit perfectly - Hallelujah! I like that this bra is not a t-back (they pull on my neck). This is quite supportive and very comfortable. I'm very happy with my purchase. I already recommended it to my sister.
