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

Great buy!

Bought 1 size larger based on the measurement (Im an M-sze based on their chart), but it still fits perfectly, just slightly longer. Very comfortable for any kind of activity, dries quickly as well. Just a note for those who doesn't like the sides to be too revealing, the armpit can be slightly only the larger end, just for your info. Otherwise, recommended!

Sleeveless

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

Best undershirt around.

This shirt is amazing. Its great as an undershirt for work but also works just like a regular muscle shirt. Its fitted but the fit is perfect.

Excellent for the weight room.

Definitely fits a little tighter. If I had to purchase again I might go a size bigger. I am 5'6 and 200 pounds, and the XL was snug.

Smelled odd

On receiving the 4 shirts I noticed they smelled a bit odd. I washed them and they still smelled. Perhaps the wicking fibers, we'll try some scent booster or other non-fabric softener scent alternative. Other than that, the shirts are working well on daily sweaty runs in August.

Too tight

Was hoping for a loose fit as my many other UA tanks.

Live it, just too long.

This shirt is very comfortable. The only negative is that it’s too long, otherwise, great.

UA slipping on sizing

The good news is the material is really nice and comfortable. The bad news is UA continues its sizing issues with this tank. It may be good for skinny runners but for the rest of us it's too tight and too long. I'm 5'10" and around 188 lbs so I'm not a fatty and the large is just too tight. I went up a size but it doesn't fit right around the arm holes and chest. UA needs to bring back its "regular" size! The loose is huge and the fitted is tight on virtually all UA shirts. It's frustrating and causing me to look at other alternatives when it seems to be an easy fix.
