Great Shirt - for use as an undershirt

I love these sleeveless shirts. I wear them daily underneath my dress shirts at work. For me, they work better then regular undershirts (cotton) or a-shirts. They help keep me cool and dry (if I sweat) quickly. I also wear them under my shirts when I workout and they just help "hold" everything together.

Sleeveless shirts

I like these sleeveless shirts,that's why I have several. It feels like you are not wearing a shirt at all. I would like to also have them a little thicker ,I wear bibs the straps wear marks on my shoulders. [This review was collected as part of a promotion.]

Great ShirtI bout these to wear as an undershirt for the polo

I bought this to wear as an undershirt with the polo, but it wears great just by itself. [This review was collected as part of a promotion.]

ua heatgear compression shirt

heatgear compression shirt is the best UA product ever made, UA should make these with the air force, navy and army logos, UA is the only product I buy these days, other manufacturers don't come close to UA, only complaint is the name, it should be UNDER ARMOR not UNDER ARMOUR, keep up the good work and please make more products with the American flag and US armed forces logos

Very reliable

I have a few of these in different colors; so comfortable I use them as undershirts. I order a size up.

The Classic Undershirt

The sleeveless t-shirt was the first UA product I ever purchased all the way back in 2003. There have been many changes, but this is still my go-to undershirt. If I had one complaint, it'd be the decision to move the UA logo to the middle instead of keeping it on the breast. I live in an extremely hot and humid area (Houston) and like to wear this shirt beneath my work shirts, but if it's a polo or button-down, the logo is visible and isn't very professional looking.

Chafes body espeically the seams

I like the quality of the material and have liked all UA products but these chafe my body especially at the seams which are very prominent with threading. I bought 3 and all 3 do it. They actually run a bit big considering they're supposed to be Compression fit


Shirt runs a bit too big. Although it is a compression shirt it fits loose on the shoulders. A bit disappointed that it is not as compressed as I thought.

Perfect fit, wish it were blacker

The fit, as with all UA garments I've owned, is almost perfect. That's clearly where they've spent their effort, and it's why I buy UA. This one runs a bit long, but it's not uncomfortable. I guess the designer was deathly afraid of anyone seeing a belly button when you stretch for something high. Get used to it bunching a little, or tuck the last few inches in to your pants. No problem. It's called "HeatGear", and I was a little worried that'd mean it'd be too hot to wear when it's hot out, but actually it's fine. It breathes about as well as any other UA fabric. Now, the (only) bad part. As Nigel Tufnel of England's loudest rock band would say, how much more black could it be? Sadly, quite a bit. I understand you have to stamp your logo on the thing somewhere, but front, back, *and* a big stripe across the collar? In addition, the seams are all gray, which kind of makes it looks like they ran out of the right color thread when assembling it. I sometimes work on the stage where I need all-black, and if this were pure black, it'd be perfect. Dang, so close! Oh well, I'm just too old to understand why these lines look cool. The other color choices are kind of dull, too -- when I'm working out, the last thing I need is more blue, gray, and white athletic shirts. Yawn. If this came in pure black, I'd buy 10 or 20 of them so I never run out. If this came in some brighter and more fun colors, I'd buy a couple more for working out. The fit is great, though, so if you like the color choices, go for it.
