Not as expected for ME

ordered both M and L - LARGE was too big, Med was too tight in armpit area.

Too short in length

For me these shirts were too small, meaning in length. They sit just at the waist line. They feel like a shimmel and if I pick up my arms they go up my rib area. I bought these shirts years back at academy and still fit perfect. Too bad I took the tags off already if not I’d return them. I wear under armour everyday, but just disappointed on these new ones.

Favorite Go-To shirt for high intensity training!

For me it's the ideal shirt to perform training session that will require lots of movement and will break a huge sweat! Doesn't stick to the body, keeps you cool and keeps its shape even if damped.

So Comfortable

This shirt fits exactly like the same size in any other brand I've owned so sizing is true. The material however is the most comfortable I've ever worn! It is very light and even a heavy sweat tends to dry within a half hour. It also moves very well with your body and does not feel restrictive at all. This was the first of many products I've bought that has put my faith in the UA brand. Will not buy anything else as long as they maintain this quality and comfort!

A great fit

Bought on line for my husband and he loves the way it looks and fits. So easy to shop and get the size you need.

Best shirt for the job

I have about 15-20 of these shirts in almost every shade and color and they all generally fit the same. I am about 5'3.5" and on the significant muscular side. There aren't many shirts that fit me due to my build but these shirts fit nice and loose on the torso and tight on the arms and upper body (more accenting instead of "cutting off circulation" tight, gives you that Dwayne "the rock" Johnson look). I work as a personal trainer and rely on these shirts on a daily basis because they work perfect for while I am with my clients and when I workout. I wish they had a bigger selection of these in Canada. The U.S. has more selections of colors. If you are someone who works out and has a very muscular body type, these shirts fit well. I wash them all 1-2 times a week and they withstand being cleaned that much with nothing being ruined. Definitely one of the best shirts on the market.

Under the dress shirt

Both 10 white shirts to my husband to use under the dress shirt. However, the logo see through of the majority of the shirts. Perhaps, the logo on white could be on soft color such as gray or white as many other design of UA (white/white)

Awesome Gym Shirt

Love the lightness of this shirt. It’s great for the gym or a summer afternoon shirt. It breathes really well.

Sizing it slightly odd

I'm 165 6'0, lean with some bulk. So, even though the sizing chart for the short sleeve is the same as the 1/4 zip long sleeve(which fits perfect), the shirt somehow fits oddly tight in the chest and arms. There's another review here explaining this exact phenomenon. Would love to love this shirt, as it has a tendency to make me look "swole-sauce" in the gym, but I need it to fit a little more comfortably, and if I go up a size it won't fit at all. Did not return, as the shirt fits to an extent, just wish it was more proportionately consistent. Plus, I get a small, but no tall option, would be amazing if that could happen. You can see in the attached photo how the sleeves taper in under the armpit.. you feel it most in your lats and rear delts where there is no room, pulling the shirt tighter around the chest and arms.

Amazing performance but...

The feel is amazing, the color is perfect, but I feel like it is just a little bit long. Other than that, the tshirt is great.
