Not What I Expected

Originally posted on Under Armour

No, I don't recommend this

For the price, I figured the material would be higher quality. I like the cut but the fabric is almost sheer and feels cheap.

Hi, Gabi! We're so sorry we didn't knock it out of the park with the material of our tank for you. That's definitely not the vibe we were going for. This tank is designed to be light and breathable, but we're sure we can find something that would work better for you, like perhaps our UA Varsity tank, which is made with thicker material. Please look for an email from me so we can discuss!

Lightweight and Cute!

These tops are perfection! I have it in 5 colors and am hoping UA will make them in so many more. In terms of sizing I am 5’4”, 158 lbs, 34B and I wear a size small. I have an athletic upper body. They wash and wear wonderfully with no fading or shrinking. Very comfortable too. I typically pair them with the high waist leggings. Highly recommend for workouts.

Perfect top

Originally posted on Under Armour

Yes, I recommend this

This top fits loosely to allow air flow. Great fit and material. I've purchased 6 of these. It works perfectly with pickleball skorts and shorts as it's shorter than most tops, but not too cropped.

Perfect light weight workout too!

The Armour work out too provides jobs at the right amount of coverage for many workout. I practice hot yoga but prefer a little more coverage than some of the girls in my class but this top still allows my skin to breath and I don’t get too warm during the workout. I highly recommend this top to anyone wanting that same benefit.

Absolute Favorite Tank!

Originally posted on Under Armour

Yes, I recommend this

This tank top is the best tank top ever! Perfect length, not too long, and just enough it covers your tummy. The tank is comfortable and isn't hot. I would recommend this tank to everyone!! My usual size is a medium and it fits me perfectly. I have the bright blue and I love it. I have the light blue and I love it. Looking at getting more colors!

Comfy. They have many colors: classic, bright, cute. I love them all. Material great for body. It sit loosely which is perfect for me. It lets my body breathe and doesn’t become wet when am doing my workout.
