Sizing off

Originally posted on Under Armour

No, I don't recommend this

This bra was an entire size too big in the band and the cup, but it seemed like it might be a good one in the right size. Might try again.

Best sports bra. Keeps everything in place without a uni-boob. And no annoying removable pads

Great support!

I love this bra because it offers so much support but is also really easy to slip into and out of unlike many others. I prefer the cross back style but I like that I can customize it either way!

Great for those with shoulder issues

Originally posted on Under Armour

Yes, I recommend this

This bra is great as it closes at the back. Therefore no pulling over your head especially with shoulder issues. I have purchased in black, white and this pink colours!

I have never been able to work out wearing just one sports bra until this one. This is IT. SO supportive and comfortable, even after a 6 mile run! I will be buying more.

Really like this sports bra as the straps can be crisscrossed or the regular way. Versatile and supportive. I also have it in white.

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

Originally posted on Under Armour

Yes, I recommend this

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.
