This Is It
Incentivised review originally posted on Under Armour
Yes, I recommend this
This is the high impact support bra we’ve all been searching for. As a relatively petite (5’5”, 120 pounds) marathon runner with implants, I’ve needed a sports bra that actually provides true, high impact support while being comfortable enough to withstand 60 miles a week of running. This bra is it. Worn cross back, there is truly no bounce yet the rib cage band is not so tight that it restricts breathing. I’ve tried Brad advertised as high impact from literally every brand and none have performed like this one. Highly recommend for athletes who need true no bounce support.

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.
No bounce for runs
Incentivised review originally posted on Under Armour
Yes, I recommend this
I've tried a bunch of different bras for running and this is the first that actually eliminated almost all bouncing and is not super bulky. For reference I am 5'8", 145lb, 37" bust, 29" waist, short torso. Ordered S D-DD (I'm a 32DD) and I can't clasp it past the loosest hook. At first I thought it might be too tight around the band but it worked out fine during a 2.5mi run (no interference with breathing or feeling squeezed, or digging; I forgot it was there at all), and I expect it may stretch out too, so I'm sticking with this size. I normally prefer unpadded / removable pad bras, but I didn't feel like this made me look too big or bulky.

Supportive and comfortable. No bounce and no chaffing. My search for the perfect sports bra is over.

LOVE it, but there's one minor issue
Incentivised review 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
Incentivised review 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!
Not a High Impact Sports Bra
Incentivised review 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!!!

Perfect for workouts

[This review was collected as part of a promotion.] The UA Infinity 2.0 Mid Impact Bra is super comfortable, supportive and perfect for workouts. The adjustable straps and breathable fabric make it easy to wear all day. Definitely one of my favorite sports bra.

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!!!

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
Incentivised review 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

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.

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

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.
