Love Running in This Singlet

I love running in this singlet. It looks nice and feels comfortable on hot summer long runs. I just ran a full marathon in it and plan to continue running in it for months to come. It is very high quality and hasn't shown any sign of age despite heavy use. Would highly recommend.

Effective buy

My husband loves this shirt. He wears it a lot to the gym but also wore on our island vacation. It keeps him cooler then normal and still has soft texture material [This review was collected as part of a promotion.]

Feels great

The shirt is a loose fit which in my opinion is great for running, which is what I bought it for. Lightweight, breathable and good quality. What more could you ask for? [This review was collected as part of a promotion.]

Worth it

Very good fit, after 45 min of jogging and running the fabric doesn’t stick to your body making it more bearable to continue. [This review was collected as part of a promotion.]

EXCELLENT running tank

Running in the Florida heat & humidity during the Summer can be a pain in the butt --- but this tank does a great job of helping to whisk away sweat and keep you as cool as possible. Definitely two thumbs up! [This review was collected as part of a promotion.]

This is one of the most comfortable items purchased from under armor.

This material is great, very soft and great in the heat. The color is fantastic and the sizing is perfect. One of the many fantastic products I have purchased from under armor. I'm sure I will purchase many more items like this, you need to enlarge the number of colors available. Thanks again for another great item.
