Hi, Lily! So glad to hear you love our bra, but straps that don't hold up isn't the move. Like you, we expect more from our gear and are sorry that happened. Please look for an email from me on how we'll take care of this.

Very comfortable sports bra

Yes, I recommend this

I was sceptical about whether one size for cups A-C would work but it’s fine. I’m 36 C and followed the size guide and bought M. Very comfortable indeed and (a big plus) no digging in at the back so a smooth look under tops. I did tip out of it a little bit when bending down but nothing drastic. Apart from that it provides good support.

Runs Large. I am returning and reordering in a Medium. The overall quality looks very good. The adjustments look very good as well as the straps which are a nice width for comfort. Looking forward to the new Medium size.

Best Sports Bra Ever!!

Originally posted on Under Armour

Yes, I recommend this

I've worn a lot of different types, styles and brands of sports bras over decades of exercise and sweaty activities. For D-DD gals, sports bras are usually painful, and with cross back straps I get migraines and arm tingles. I found this sports bra and immediately bought 5 more - the combination of structured support, adjustable straps, non-cross back make this the most comfortable, supportive sports bra I have ever worn. Never stop making this! And more colours!

Good support, versatile

Originally posted on Under Armour

I bought this bra as I have a hard time finding the high crossback bra, which is always out of stock. It was supportive for tennis in both configurations, but not as comfortable as the high crossback bra with the straps crossed. I am a 32dd. Would buy again.

I was so happy to find this style exercise bra. I cannot wear the razor back style because they make my back and shoulders ache. I wear a 36C regular bra. I ordered the large in this style (which is what the chart says is my size). I couldn't wait to get these bras. Well I am so disappointed. Should have went with my gut and order a size down. It is huge on me. I had it on the inner most hooks and it still bagged. It would offer no support with any type of exercise. I will be returning. I can't oreder more because they are all out of my size now. I hope they get more in so I can order a size down! I loved te color and style of the bra. Hoping when I get ot order new ones they fit.

Love the contoured cups, super comfy

Yes, I recommend this

Love the contoured cups, super comfy, I’m a 34B and the bra is great for running, gives me support and I get to keep a good profile. Bra’s that fit are so hard to find. Would prefer the brand wasn’t all over the straps but it’s a trade off.

The perfect bra

Originally posted on Under Armour

Yes, I recommend this

After 55 years of searching, I am grateful to have finally found the perfect high impact bra. I live in Florida and walk and jog twice a day in 90 plus degrees, so I must change into a clean bra at least three times a day.The UA Infinity 2.0 high impact is very well constructed. I love the wide adjustable straps, molded, non removable cups and wide sides. Double stitching makes these bras very durable and stands up well to frequent washing. The are breathable and comfortable enough to be worn every day. I wike these bras so much I own five pair: three high-inpact and two medium impact.36 D size L KUNDOS UA, please do not change a thing!

Hey, Bella! Uncomfortable bra straps is not the vibe we were going for and we're really sorry that happened. We want you to feel comfortable and confident in our gear and are sure we can find something that gets you there, such as our UA Infinity 2.0 High Zip, which features a different strap design. I'll send an email with more details.

Loving My UA Infinity 2.0 High Sports Bra

Originally posted on Under Armour

For me, the best part of my new bra is the total coverage, and the adjustable straps. The bra is comfortable, and seems to wash well. I also like that the cups are firm and keep everything in place. I will be purchasing another soon!

Not impressed with this bra

Originally posted on Under Armour

No, I don't recommend this

The fact that this bra hooks like a regular bra is a plus. I hate bras that go over your head to get on. What I do not like is the sizing. Small, medium, large, X-Large sizing does not work for a lot of women, neither does cup sizing A-C, D-DD, etc.

I love that this sports bra is supportive but also fully adjustable in band width and shoulder. It also has the option for a cross cross back.

BEST SPORTS BRA EVER

Originally posted on Under Armour

Yes, I recommend this

I tried this bra because my sister recommended it. I would not have thought, by looking at it, that it was so fabulous. The hold is great, but my favorite part is the shape! I don't look like I am wearing a sports bra at all! So if I leave the gym and go elsewhere, I feel confident no matter what I am wearing.

Good Running Bra

Originally posted on Under Armour

Overall, it is a good running sports bra. The straps are adjustable which is a nice feature. The only thing I really do not like is the width of the band. It is a bit too wide and rolls up on itself.
