Love it!

[This review was collected as part of a promotion.] Runs a little big, but I wanted a loose fitting tank and this definitely fits the bill!

Knockout Tank

[This review was collected as part of a promotion.] This racerback tank is awesome! Great fit, casual and sporty, goes great with Under Armour racerback bras. You feel great, whether you are working out or if you just want to be sporty. This tank is a definite head turner, so many compliments and questions as to where I got it. Right there on the tank baby, "Under Armour"!

Love this top

[This review was collected as part of a promotion.] Its is a nice color. Fits well and so comfortable. I would buy more if they had them in different colors.

The Knock Out Tank is AMAZZZZING

I literally have purchased EVERY color and I am hoping they come out with more colors in plus sizes! I first purchased the black one, then the mint, purple and now the grey/navy. This tank fits me perfect, I am a true 18/20 and get the 3X and it is flowy and perfect to pair with my UA plus twist shorts or my UA leggings. Thanks for making us plus size ladies feel great in UA!!!

Great top

Super soft, fits well, so comfortable. Does not get tangle in the bar when I’m lifting. Love this top

not for long torsos

i’m 5’9 and I have a normal/longer torso and honestly just like my shirts to cover my bottom area and this tank top did not do that for me. it fits well and is so cute, it’s just too short for my liking
