shorter length and lower on the chest

I have several momentum tanks and they are my go to. However...this new version did not work. Runs small, lower on the chest and shorter on the body. I am really sad that the regular momentum seems like they are phasing it out. This new one is not a good replacement. I have a longer torso but even s...

Momentum Flex Tank vs. Momentum Seamless Tank

Not sure whether Athleta launched the new Flex Tank to replace the Seamless Tank or not, but it would be helpful for Athleta to add the differences to the description. Especially important to me is the length of the tank (in inches). I much prefer the original seamless tank because of its extra leng...

Comments about Momentum Flex Tank

I'm obsessed with these tanks and have four different colors now. They're super comfy, very breathable, and are in fun colors. The inside of the bottom hem also has some rubberized grip, so the top stays put even through a lot of moving around.

Love these tanks

Comments about Momentum Flex Tank

This tank manages to be thick enough to smooth over any bumps while being thin enough to breathe. I wore it on a 100 degree day and it was perfect! And I ADORE the Siren color. Such a great color for summer and everyone I was with loved it.

The color is amazing!

Comments about Momentum Flex Tank

I'm so glad to see this beautiful color as an option. I'm so tired of everything being neutral colors as not everyone looks good in browns, beiges, etc. The material is nice and has grip material along the hem to prevent riding up.

Flattering tank

I own probably 25 of these Momentum Flex Tanks. They fit perfectly and are not cropped. True to size and wash up well.

Perfect for workouts and layering🙌
