Too long

We like a singlet shirt with fitted arms or not low under the arms. This singlet was good fit and well made/comfortable but too long.

Misleading Label

It seems Under Armour (once my very favorite) has decided to stop making true sleeveless t-shirts and is making only tank tops. I wear sleeveless t-shirts under Polo shirts - a perfect combination. Your mislabelled sleeveless t-shirts all have large arm holes - if you don't remember, a sleeveless t-shirt has an arm hole the same size as a regular t-shirt's, but without the sleeve. I'll be back when you stop making basketball jerseys and calling them sleeveless t-shirts.

Not enough cushion

My regret is I didn’t try them on as soon as I received them, seems the left sneaker is defected . The padding seems thin on the insert .

Great shirt - runs longer than past shirts

So I will admit that it has been years between my purchases (same shirt, size and fit) but it still fits perfect on the shoulders and chest but I find the shirt longer now. If it was 1" shorter, it would look perfect. Comfortable. A very good workout shirt. 4/5 stars

Sleeveless

This product is great but not as comfortable around the neck as the slight V neck of the old UA sleeveless.
