Only high Impact I get

Originally posted on Under Armour

Yes, I recommend this

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!

The back straps are horrible

Originally posted on Under Armour

No, I don't recommend this

The straps being crossed makes it’s 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 it’s so frustrating. I have always ordered this size for years so it’s definitely this bra

Best Sports Bra for Chesty Ladies!

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.

Best sports bra

This bra is so comfortable while supporting well. It washes great and I don’t 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. It’s 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.

Great support

Originally posted on Under Armour

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.

Originally posted on Under Armour

So now that I’m in my 40’s 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 ‘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)

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!

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

Originally posted on Under Armour

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

Originally posted on Under Armour

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!
