I work in a kitchen and wear this bra for 10 + hrs. Doesn't feel tight or leave marks. Plan to by more.

Hey, there! We're bummed to hear our sports bra didn't provide the support you were looking for and appreciate you for trying it out. We want you to feel confident and comfortable when in our gear and are so sorry that didn't happen. However, we're sure we can help you find something that would work better, like perhaps our UA Continuum High bra. I'll reach out so we can discuss!

Excellent for larger chests

Originally posted on Under Armour

Yes, I recommend this

I have tried a million sports bras as a larger chest smaller bodied girl and it is so frustrating! But this bra by UA comes so close to being perfect! I love it and I highly recommend. It keeps everything in place snuggly but I can still breathe. Love the adjustable straps. The ONLY thing I wish is that the back strap where the hook and eye closure is was thicker. Other than that, great bra

Great Bra. Great Support

Originally posted on Under Armour

Yes, I recommend this

I love this bra so much I bought a second. I love that the straps are convertable for more options. You get full coverage with this bra and great support. I love that you can almost customize the size you get so that the band and bust are more accurate versus a simple Medium/Large, etc.

Fit Poorly, Stiff as a Board

Originally posted on Under Armour

No, I don't recommend this

I’m 32DD, I got a small DD and a medium. I have fake boobs so my support needs aren’t as significant as someone with my same size and real boobs. I usually buy a size small for just regular non molded sports bras. If you like sideboob, this is your go-to bra. This did not cover my boobs on the side of my body, all the way up to the front, the front was cut way too narrow, the sides were way too narrow. It was like wearing a halter top that cuts in by design, except this was not a halter top. This was the case for both sizes I got. The molded factor of the bra is…not great. My sport is running, I still had bounce, but my main complaint is that whatever shape my boobs have, this thing is so stiff and hard that they did not look like mine. They looked like whatever UA thought my boobs should look like, which to me was kinda weird. I returned both of these and tbh, all o really need is the compression bra you guys make with, have it come slightly higher up, with an option for d/dd.

Hi, Krissy! Thanks for the real talk! We appreciate this honest and helpful feedback, as we are always looking to level-up our gear. Quality comfort and adequate support are the game-winning combo when it comes to sports bras and we're sorry this one missed the mark. We're sure we can find you another, however, like perhaps our HeatGear® Armour High bra, which may have the fit and feel you're looking for. I'll reach out shortly to get more details. Talk to you soon!

Excellent Support

Originally posted on Under Armour

Yes, I recommend this

Highly supportive sports bra at a reasonable price in relation to the quality. Molded, padded cups that still provide adequate ventilation as advertised. The bra and straps are NOT particularly stretchy which is a good thing because it means better support. I've used this bra for marathon and ultramarathon distance runs and it stays put without chaffing. For usability as an everyday bra with any clothing, I wish that a greater selection of subtle colors without contrasting visible UA logos were available. I would purchase more. The adjustability from side/regular straps to crisscross is an excellent feature. My single suggestion for improvement is to move the hardware for detaching and adjusting the straps from the front to the back. Right now, this location of the hardware means I cannot wear this bra when using any kind of backpack as the straps would uncomfortably press the clips into my skin. Even on a short run or hike, these spots would have wounds. While you could no longer adjust while wearing if the adjustment clips were in the back, it would eliminate the pressure points.

Good ! recommend!

Originally posted on Under Armour

I’ve been using the UA Infinity 2.0 High Sports Bra for a few weeks now, and it’s amazing! The support is super comfortable but strong enough for running and intense workouts. The straps don’t dig in, and the material is breathable — no more feeling sweaty or restricted. Plus, it stays in place the whole time! Definitely worth it for anyone with an active lifestyle. recommend!

Heavy duty for high impact

Originally posted on Under Armour

This is a serious bra - very ridgid and dense. Might be better suited for cooler weather as it retains a lot of moisture when you get sweaty.
