Not red, more of an orange

It’s great tank top and the XS fits perfect, I’m 5’4”, 32 A, very slim athletic build, but I got it specifically to go with a pair of Navy and Red Under Armour leggings and sadly it doesn’t match. The color isn’t red so much as it is orange. Unfortunately I am going to have to return it. I know it sounds silly but when I’m competing I like it when my outfit matches.

Superb Qualty

Best top ever

[This review was collected as part of a promotion.] I would highly recommend this shirt. It fits loose and super comfortable. Also very flattering on the body. Great too.

Soft and light weight

[This review was collected as part of a promotion.] When I ordered this, I couldn't tell if there was a sports bra attached. There is not, but I recommend this shirt anyway. It is super light weight and soft. I wear it for running and it does not chafe at the armpits.

Great tank top

[This review was collected as part of a promotion.] I love the fit and the look of this tank top. The material is light and breathable . Perfect for working out or running. Looks GREAT!

Luftiges Top

Das Top fällt schön luftig aus - schön bei heißen Sommertagen. Habe es in Größe M bestellt und es fällt locker. Spannt nicht bei großer Oberweite (75E) und kaschiert kleines Bäuchlein. Leider reibt es etwas unter den Armen am Netzstoff beim Laufen.

Very Comfortable

[This review was collected as part of a promotion.] This is a great loose fit tank for running or gym time.

Got many compliments on this top

[This review was collected as part of a promotion.] I purchased this top because I had already purchased it in blue and loved the way it fit. It is roomy and has wonderful detail. The color is vibrant and the complimentary color adds to the overall look of the top. I purchase my workout clothes from you because of the fine quality of Under Armour clothes.
