Good support

This has good support. I think I would like it better if the neckline came up a littler higher for more support and enclosure vs the lower cut, but it works.

Fantastic fit

This is the best fitting run bra I have ever worn. It provides excellent high impact support. The straps may be worn cris crossed or regular. This works well for racer back tank tops so there is less of the bra showing. I got the lilac and the dark green colours. Both are very pretty. The fabric is soft and so far no chafing. Overall an excellent product.

This is high impact and gives support but the straps do dig in some.

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.

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.

The perfect bra

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!

Straps are not comfortable for the price you pay I expected a better quality!

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.

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!

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.
