Wow, the material of the shirt has an absurd quality!! It is different from other brands, it has an incredible softness!! It is not dry or rough!! The quality is really superior to other brands!! I run and do weight training and I am surprised by the comfort of the Under Armour brand.

I have six knockout tanks from 2 years ago and I LOVE them. They’re more than active wear, they’re often daily wear. And I was so excited to see a new color other than black available in plus size, I jumped on them and ordered four more.Extreme Disappointment is an understatement.UA, you had exactly one functionally loose fitting plus size shirt, and you had to mess with it.The new tanks have an inflexible neck hole and the neck line has been raised to the throat. The arm holes are too tight, and it’s cut to expose your chest on either side.To anyone who found the original knockout tank comfortable and a “go-to” garment, these new ones are unwearable.

The idea of having a bra/crop top within a tank really appealed to me. As a larger busted woman I need the extra support, so I was excited to try out this product. I love the material quality and the design. It is really fashionable, cool and comfortable. However the shelf bra itself is almost impossible to get on and off if you follow the recommended sizings. I bought a medium which is the size recommended for my chest measurements. It is a REAL battle to get on and off, as to have it tight enough to work properly as a shelf bra, you struggle to get it over your shoulders and chest. It really needs a clasp at the back. Otherwise I really like the top.

I love the fit and comfort of this tank. I'm a 36 DD and the large is perfect. Loose flowy fit. Cute ,stylish style .Nice length to cover my butt and mommy belly. Perfect with bike shorts. I'm going to get more colors.
I wore this on a pretty hit & humid Iowa day to a golf tournament only to get a large, wet "swoobs" area. I loved the color, the weight and the feel but was sad to find it was really not a breathable material for these conditions. It did seem to dry quickly once we were done and in the AC, but it wasn't pleasant.
I love these tops and the Heatgear works for me i have the hsorts too and i love them.BUT looking closer at the top on the photo mine are dfferent they do not have gaps at the sides of the top and im unsure what else is different if the design can be totally different to the photo what else isnt right.I ordered all colours GREY PINK BLACK WHITE & I re ordered to ensure this was a mistake and it isnt. They came the same again no slits/gaps. I informed very but keep getting different people speaking to me so its stll unsolved. Why cant someone just get this sorted instead of saying re order it may be a problem with the item numbers. Starting to loose hope in VERY customer service I am having so many issues from collections not turning up to things not getting ...

I would love to know what tops i have because they are not these
This product doesn’t shrink. Fits perfect after every washing. Light weight. Breathable. Soft. Stays white. Matches any pair of shorts. And breathable leggings. Goes great with any pair of Undrr Armour shoes
This certainly could be a fabulous top for some. The color selections are great and it is very nice fabric. The fit is just not flattering at all for my body type. 5'8, 135 lbs size small. It is very boxy and shorter than I would like. The fit is like the Halo Gray model and the Mauve color as well. Flows out and is "tent like", not flattering. The top runs very low in front and will expose your sports bra. I really wanted to love this. I am going to try another tank instead. Please bring back the Accelerate tank....absolute favorite!
I bought 2 years ago white and I matched it perfectly in sports. Now I wanted a black one and ordered it. The shirts and sizes should be the same, unfortunately the stitching on the chest was very different. I could have returned it and tried another one, but since the quality of the material itself and its appearance suit me perfectly, I took it to a tailor to have it corrected at the chest according to my measurements :)
I am already an Under Armour tank fan girl, but this tank is my absolute favorite. I came across it by chance while shopping in-store. While the store did not have size, I was able to order 3 colors online. The shipping was fast and the tank did not disappoint. If these are restocked in my size, I will purchase more!
