Great top, fit is perfect (but you MUST SIZE DOWN) material is lovely and very breathable for training. Recommended but cannot stress how much to size down - I’m normally an 8 and had to buy XS (2-4!)

Very light fabric, not sticky, perfect for outdoor activities. Very cute. I'd love to get it in more colors. I'm 5'3" and athletic built, bought XS, fits perfect.
Lovely light weight material. Love the under armour writing on the straps.
This is a nice colour and style. Does run quite large. I think it would be ok for the gym but the material is very soft and does not feel like it would be cool enough to run in.
I order TWO of the knockout tanks. Both came in a few days apart but no worries. I really like these tanks and wanted these tanks but for some reason you all sent me not ONE but TWO WRONG SIZES.. I ordered a black in a size M and you sent me a size S. I ordered a navy in a size LG because you were sold out of M and I can get by with a LG; however, you send me a size XL. I’ve returned one. I will be returning the other. No sense in me keeping something that I CANNOT wear. I’m extremely disappointed.
The writing part round the sides rubs on the inside of my arms has made them sore when running, so no good for running but just to wear for yoga and gym it’s ok. Nice material.
good for those days you feel bloated and you're wearing tight leggings. Its a bit pricey for what it is though. I bought before it came down in the sale
Nice basic tee, bought it mostly for color. The yellow and pink are soo bright and beautiful
