Love this tank

It fits super tight so I recommend going up a size. I usually wear a S or XS and I bought a Medium. It's still a bit tight.

You'll need to size up

The colours are amazing. However, the new style for this tank top is thin, super form fitting and short. I'm usually a medium and find that it has a bit of room (which I like) so ordered this in a medium and its far too small. I need to return it. Not sure why Athleta thought they needed to chan...

I wear an XS in the other Momentum Flex Tank with thinner straps (the one that comes in short sleeve / long sleeve / sleeveless), and often wear XS in other Athleta styles. I ordered this in a Small based on other reviews to size up, and I should have gone up to Medium or even Large.

I wear an XS for all Athleta tops, including Momentum tanks. This style runs so small that I needed a Medium. I don't care what the label says, and I do love the Momentum line. It's just SO strange that this style runs so small.

Comments about Momentum Flex Muscle Tank

This is my favorite tank. It is so versatile… casual or a bit more dressed up. It's a great classic cut and the perfect length, not too long and not cropped like so many tops. It does run super small. I am normally XS or S in tops but needed a M in this one.

I ordered a small when I usually wear a small or xs and it's very small. I would size up at least one size. Comfortable fabric though.

I'm 5'8", 133 lbs and typically wear a medium in tops, even a small in some styles, but had to size up to a large. The fabric is thicker with less stretch/softness than anticipated, but I do really like the waist length and the silicone grip around the bottom band.

Comments about Momentum Flex Muscle Tank

I bought a size larger than I usually need as Infound this tank very fitted. But I love the cut of the arms on this tank. I have some other muscle style tanks I wear for lifting of barre class that rub. This tank's arm holes are perfect. Also like the contrast on the tank. Adds a little something fun to my usual style. #sweepstakes
