Under Armour Crossback Mid Bra Black - S

$39.99

(1,293 reviews)

Sports bras shouldn't be complicated. They should be comfortable and provide support. Under Armour tackled this issue at its core by asking women how their favorite bra could be improved. And guess what: it worked. The Armour Crossback Mid offers strategic support for medium-impact activities like cycling, strength training, and boxing. The super-smooth, double-layered HeatGear fabric provides a second-skin feel. The lightweight material also wicks away sweat for dry comfort. The crossback straps with a modern keyhole detail and the elastic underbust band featuring UA logos ensure an optimal fit. The removable bra cups are soft, quick-drying, and perforated for high breathability. Plus, they can be easily reinserted after washing, thanks to helpful arrows indicating right and left.

The bra went on easily and gives me enough support for weightlifting or some light cross training. The bottom band is a bit snug, which is a good thing for me, and it hasn't rolled up yet. The sides of the bra are wide enough that it doesn't make my back look flabby. The pads are a good size and do truly keep everything smoothed out.

Cheaply made with zero support

Cheap material that is extremely over-priced for quality. Bra stretches extremely easily, the band provides zero support and over stretches within one wear. Washing it does not shrink it back down to size. Waste of money and I do not recommend it.

Comfortable and supportive

I bought this sports bra a few weeks ago and it does everything I need it do to. I do some cardio when I work out and so I need something supportive. So many sports bras are just cute and is only fabric covering the girls, which is fine for those with smaller chests. This bra is great, not too tight where I feel like I can’t breathe, but is supportive while I’m running, jumping, doing mountain climbers, etc.

Comfy everyday wear
4 October 2021

Good comfy medium support bra. The inner pads dont move around which is good. Doesn’t dig in anywhere either. Washes well and dries fast. If you’re used to wearing a crop style bra you’ll like this one. Easy to put on overhead and it doesn’t have clasps to scratch the skin. My only dislike about it is that it doesn’t really ā€˜lift and seperate’ like some bras lol it kind of pushes boobs together so it can sometimes look a tad unflattering under sports singlets. I think it’s good for low impact exercise and every day wear but if your doing any kind of high impact running/jumping etc then get a more supportive bra.

Great even for Large Bust
13 September 2022

I was pleasantly surprised that I could wear this bra and not feel too uncomfortable. I love the cross back style sports bras, and this one fits well. I always struggle with this style due to larger bust size that needs a size large, but a rib cage that needs a size medium. The girls are a bit smooshed in there, but it fits really well and is supportive and to my surprise the rib band is not scratchy or uncomfortable!!

Just right
26 September 2021

I got a medium, and worked for me. I'm a 36C at my heaviest, and a medium works. It's quite difficult to put on because the material doesnt stretch easily, and it's a crossback. Other than that, I have no issues with the bra.Gives me great support when I run, snug when I need the girls to be held in. The band is wide enough to prevent the boobies from spilling out from the bra when doing vigorous exercise.

Older version was more comfortable
10 April 2021

It’s a good sports bra just way more uncomfortable in my opinion compared to their first version of the keyhole sports bra. It comes up way higher on your chest than the UA sports bras I am used to. I liked the wider coverage near my armpit that they took away with this version. Not a bad buy I just couldn’t get over how much the shape changed from the OG keyhole ā€œheatheredā€ sports bra. I found the lower band way more slippy if you know what I mean. I returned it and ordered the older version online.

Perfect bra after breast surgery
25 April 2022

I coincidentally bought this bra before my breast surgery and I did not have the chance to wear it. Finally, 3 weeks after the surgery the doctor allowed me to exercise so I went cycling on the first day, and this bra held my right breast perfectly since it is not too tight and my breast had enough space; I did not have any pain at all! Then I went hiking on the next day and it also helped me with my breast, it did hurt a little while hiking down, but it's absolutely normal after this painful surgery. I am sure I'll be able to practice any sports without pain and with great support once I heal. I'm absolutely in love with it and I'll be buying more for sure!

Sizing with Asos is shocking
22 August 2022

Always had medium with under armour but it arrived super small. I re ordered a large and fits perfect. I'm a 10 in most Tshirt tops. 32DD. Large fit better than medium. Hope that helps. I love the style of this bra I have it in 4 other colours... Super comfy to

Sports bra
15 February 2023

The pattern for this bra is so cute how ever looks can be deceiving. I bought a large being that all of my other under armour bras are a large. It is very supportive how ever the fabric is not comfortable. The seams are itchy and the fabric has rubbed my skin raw. Over all I’d say this purchase was a waste of money.
