UA Infinity Bra

Fit true to size, but not a fan of the mesh. Just not for me but overall a good bra.

The sports bra I've been waiting for

Originally posted on Under Armour

Yes, I recommend this

I'm a runner and spinner and I've tried every expensive sports bra brand out there. This is the only one that looks great, feels great and gives me the support I need without rubbing on my skin. The approach to fit - 3 cups at once, is awesome. Highly recommend!

I have to admit, I was a bit skeptical to order a sports bra that hooked in the back, like a regular bra...BUT, I LOVE it! Great support, comfort, and the perfect fit for my strength training sessions.

I needed new sports bras postpartum. My first go to is UA, as I love all my UA bras and have been wearing UA sports bras for almost 20 years. This bra is so comfortable and more importantly, provides great support while exercising. It is also excellent quality!

Great high impact sports bra

Comfortable, cute colors, true to size. Provides support for high intensity and high impact workouts like HIIT and running, without digging into shoulders or back.

Best bra in forever!

Originally posted on Under Armour

Finally found a bra to support my, in the way, double DDs. I bought a 2nd bra so I can use these as my every day bra. Since my TBI and very lengthy ongoing concussion recovery- years of medication put on a lot of weight(50lbs). Now that I’ve found a bra that doesn’t make me feel frumpy and fits as a bra should - I’m gaining more of my confidence back and find it easier to get out of my own way and get on with living!

This bra is comfortable and supportive. When I wear it, I forget its there like some sports brass and bras in general. It's super supportive and eliminates bounce. It looks pretty too. I got the Grey and it's a lovely color.

I hate this so much

Originally posted on Under Armour

No, I don't recommend this

I have never disliked an UA purchase before. This bra was intended for running, but it holds nothing still. It's not comfortable, and the shape of the cups is apparently for people who are super saggy - extremely low in relation to where the band sits. I read up on the sizing and used a combination of reviews, measuring tape, and my previous UA running bras to decide what size to buy. Worst birthday purchase of my life, and that isn't hyperbole. Also, I don't HAVE an ad blocker, you insane software that won't let me post this!

This sports bra is simply the best! I like to have one with good support but also that is comfortable and those are hard to fine. The material is soft, breathable and very comfortable!

Best Sports Bra ever

Originally posted on Under Armour

I am a senior and have tried on dozens of sports bras with no luck. I was so discouraged until I put this one on. It fit like a glove. It’s super comfortable with the moulded cups and the straps are nice and wide. Now when I do jumping jacks everything stays in place!

Great for larger bust

Originally posted on Under Armour

Yes, I recommend this

At last! A bra for a larger bust runner that provides support and minimizes bounce. I am a 34DD marathoner and I purchased the S(D-DD) bra. The bra is snug without feeling like a corset, soft against the shoulders, bust and back, and very supportive. And no uncomfortable bounce. The only thing I would change in the design is getting rid of the padded cups. The padding is lightweight thankfully, but does add some bulk. Bottom line, this bra works! Recommended.

This bra is easy to clasp and the strap hooks stay secured. The support is great and the lower band is comfortable. I ended up buying 3 more after trying the first one I purchased.

This is the best bra Under Armour has ever created

Originally posted on Under Armour

Yes, I recommend this

I've tried so many different sports bras from both UA and different brands over the years and they all fail in one way or another. I've had this bra for a while now (back to buy more!) and its still as sturdy and comfy as the day I got it. The padded cups on the bra are amazing. They haven't lost their shape, offer a good amount of protection and great support. Since the padding is all built into the bra there is no fussing around with those inserts that always either lose their shape or get lost. I also love how easy it is to get this bra on and off. I am able to get a good snug fit very easily without having to struggle as I have had to with every other bra I've owned. The hook mechanism on the straps is super easy to use yet very durable. And finally, I actually got the correct size for my body thanks to the updated fit guide. I was skeptical when it said I would be a size XS since I have always bought size S, but now that I have tried XS (and can actually get it on without struggle!) I feel the difference. The cups on the XS don't bump into my armpit which is a lot more comfortable and now there are no gaps anywhere so I have the best support all around! Thanks Under Armour!!
