Great Tank and UV Protective

I recently found Athleta after a melanoma diagnosis this spring. I am 52 and have a very active outdoor lifestyle. My closet was full of different tank tops that offer little to no sun protection. The momentum line offers 40 UV protection and has been a lifesaver for me. The fit is great. This s...

Way Too Small

I normally love these tanks and was excited for the black with white trim to mix it up. I also bought the bright pink. Sadly, both are going back. They run super small and don't fit the same. I'm normally a M in Athleta, (5'6", 155lbs, DDD chest) but will sometimes size up for "clingy" fabric. I ord...

I wanted to find a replacement for the "in motion seamless tank" but found this style to be extremely small. I am typically an XS but sized up to a medium which works for me. Arm holes do not gape when you go up in sizing which works out well. I will purchase more in the medium.

Comments about Momentum Flex Muscle Tank

These momentum flex muscle tanks are good quality and come in great colors. However, they tend to run about 1-1/2 to 2 sizes small, and the length seems to change depending on the color. I'm 5'1", 98 lbs, and have a long torso. After seeing reviews, I went up from XS to S and got my first tank in Breaker eclipse. It's very fitted, but it still works. During a final sale, I bought a second size S tank in Cerise heather, and it's about 1-1/2" shorter straight out of the bag! I'm getting fed up with Athleta's inconsistent sizing!

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.
