Such a well-made, supportive bra. I wear 36DD and do a lot of sports. This bra supports me very 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 ‘thick’ and big but once you get it on, it looks and fits great! Fabulous quality, good fabric, supportive and ‘engineered’ 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 I’m a ‘small’ 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. I’ll probably buy another when I’ve saved up!

4 Stars (from someone who hates bras)

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!

Hi! Thank you for your feedback. I'm really sorry to see that the hook has ripped off! I got your back and am happy to help. An email has just been sent over to you so that I can step in and help with next steps. I hope you have a great rest of your day. Thank you for choosing Under Armour!
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 it’s 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. I’m really sorry the bra arrived with an odor even after washing, and that the closure felt tougher to manage than expected. I’m glad the fit worked for you, but you shouldn’t have to deal with anything that feels off right from the start. I’ll follow up with you by email so we can help make this right!
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!

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

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.

Excellent sports bra

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.

Please bring back the old style

The infinity bra (mid impact) has been my favorite running bra for years. I have had mine for over 10 years and while they have held up well, it is time to buy new ones. However, The cross back in the old bras is much more supportive. While the new bras can be changed into a cross back, due to the new location on the plastic adjustable buckles at the front of the bra instead of the back, the plastic buckles dig into my collar bones. I have not been able to find a new favorite running bra and sadly returned this bra in this new design.
