Best mid support
Originally posted on Under Armour
Yes, I recommend this
This is one of the best bras i own. they lift great, without the unpleasantness of underwire. i definitely need to get the high support next so i can use it for running and stuff. this is a great everyday bra!

UA Infinity Bra

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

So amazingly comfortable!

It looks like it would be stiff and like literal “armor,” but the minute I got it on, I forgot Iwas wearing it! I also like the encapsulation style — unlike compression style, it doesn’t push my boobs forward and make me look bigger. They are durable too, and the mid support is solid enough for horseback riding. I wear a 38B in regular bras and the L/A-C fits perfectly. Please UA never discontinue these!!!

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.

Great Fit for Strength Training Session

I ordered one Mid and one Full Infinity 2.0 Sports bras, and I LOVE them both! In all honestly, I ordered both thinking that I would only keep the one that I like best. I can't send either of them back, I really LOVE them both! My main form of exercise is strength training, and the mid 2.0 is PERFECT for those 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!

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

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

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!
