Tech™ Muscle Tank is rated 4.1 out of 5 by 23.
Rated 5 out of 5 by from Light and Great Fit Perfect update to the original UA tech cutoff. No more tightness around the armpit area. What I love about the Muscle Tank: Love - Light, sweat doesn't weigh down your shirt. - Wicks sweat very well! - Soft feeling - Looser around armpit. Perfect for lifting. No uncomfortable feeling at the pit. - Good variety of colors. I'm in between a medium and large. I ordered a medium as I know the shirt won't shrink (polyester). With UA loose fit shirts, I usually go with a medium (but only if it's 100% polyester). Will be exchanging for black color as I didn't like the green too much. Still a 5 Star Shirt! Great job UA! #IWILL

Rated 4 out of 5 by from Good Workout Shirt I like this shirt for the gym, particularly leg day. The bigger arm holes are a plus for weight lifting. I make a point of looking for sleeveless shirts like this one that have the shoulder seam somewhere other than the top of the shoulder, so that I don't get a red welt from the seam when using a machine where the weight rests on your shoulders, like the hack squat machine. Shirt runs big. I'm between M and L in UA sizing, so followed my usual rule with UA - go with M if a loose fit. This is still loose, but only comfortably so. The one downside to this shirt is the rounded shirt tail makes the shirt feel really long.

Rated 1 out of 5 by from Strange fit... I've been a huge fan of UA's sleeveless shirts over the years. I bought 2 of these and found they aren't anything like what I've been used too. The tails once again are waaaay too long and the arm holes are gigantic. The fabric is very strange, sort of a hybrid cotton and it gets very heavy once sweat accumulates. Not nearly the comfort/fit UA usually offers. This isn't a fitted or loose cut...somewhere more toward fitted yet the arm openings negate comfort and expose way more torso than needed. This isn't for me...

Rated 4 out of 5 by from Love everything except the long curved back Bought this in multiple colors in Large. I almost always wear L or XL. This shirt, though might've been better in Medium for me and sure glad I deleted the XL from my cart and got L instead. The shirt style is loose and long. Why would UA have a long curved back bottom hem though? It looks like something that would be found on a female blouse and looks silly on this shirt. I can see if the shirt is going to be tucked in, but how many guys actually tuck in their shirts like this? None that I see. A straight bottom hem on the back would've been much better. A picture on the web site of the back of the shirt along with model's dimensions would also be immensely helpful.

Rated 3 out of 5 by from What happened to the quality of the clothing? I've been hooked on UA for many years now. Lately, I noticed that the clothing prices have gone up and the quality has gone down. I compared my older UA stuff and compared it to this year's clothing and noticed that the thickness of the fabric and overall quality just isn't where it once was. What happened?

Rated 5 out of 5 by from Perfect for hot weather or to layer over a compression top This is the perfect sleeveless gym shirt for a balmy hot day. I also like to layer this over a CoolSwitch compression long sleeve..this combo really works for me at the gym. This shirt is super light and soft so it's comfortable solo or layered. I like the drop tail hem, adds a little style to an otherwise boring shirt. I drop down one size in all loose fit Tech tops because I prefer fitted over loose, i've never been disappointed with the fit or performance of UA tech when I do this. I like this shirt enough I will probably buy one more in a different color.

Rated 5 out of 5 by from Best UA Product in a While This is a great shirt and UA should definitely add white to this lineup. For people that complain about the contoured lower back of the shirt, I just say this: Clearly you're not training your legs and glutes. Remember, these clothes are best suited for athletes and athletic people. I'm 5'10" and 185 and I wear the small since my body fat hovers around 9-10%. I could wear a medium for the ultimate roomy gym cutoff look, but it just isn't my speed.

Rated 5 out of 5 by from Perfection I have been looking for something to take the place of my charged cotton sleeveless t's for a while now since I have worn those out, and I finally found what I have been looking for. These are light, loose enough for full motion but still look great, and as others have said, they are cut perfectly around the arms. With summer on its way, this will definitely be my go-to in the gym. Colors are great, and more would be even better!
