Under Armour Men's MK1 Sleeveless T-Shirt

I bought these when they were a new item and listed at $10. I've since seen them listed for as much as $30 and can't for the life of me imagine them being worth that. They make a nice undershirt/workout shirt, but my price point for a nice shirt that does those things is much less than $30. It's an excellent value at $10, but the ROI diminishes quickly at price points above that for me. Breathes well, fits comfortably.

These are my favorite sleeveless shirts ever. They are light weight but not too thin. They are perfect for lounging around the house. The only thing I would say might be a problem for some people is the fact that the arm openings are kind of wide. If you have a problem with people seeing the sides of your chest, you might want to get something with smaller arm openings. Other than that, I have no problems with these. As far as fit, I am 5’6 165 lbs. I wear the large but I could actually go for the medium as well for a tighter fit. Go one size up if you want a more comfortable, looser fit.

Great lightweight workout tank. The cut is a little weird, specifically in the chest where there's just a strange amount of fabric that it kinda pops out unless your chest is very large. As others have mentioned the armholes are larger than your typical UA tank. Also the length is longer than usual - which was actually the main reason I bought it, since I usually have to size down a bit to get a tighter fit, but don't want to be wearing a glorified crop top, so this is a nice balance. The material is nice and keeps cool easily during workouts, so I generally like it a lot.

Great product! Usually UA fits small- this is larger than expected! So if you normally wear a large for UA gear order a medium. Large is a true to size large- different from many of the other UA products we own.

UA doesn't make sleeveless like this anymore. this is the last of its kind. the newer ones have the arm holes cut so low that it just doesn't fit right. I use this mostly for an under shirt and its long enough to keep tucked to hide the dreaded plumbers crack! everyone I do work for thanks you UA!

Designed to fit based on the Underarmor fit types, this clearly is designed to be more like a "racer back sports bra" shape than a normal sleeveless exercise shirt. The armholes are long, but the chest isn't very deep, so if you have the chest of a skinny teenage boy then it might fit like the pictures and the normal Underarmor sizing. The neck hole is a bit smaller than the normal size, so very tight, and the shoulder width of the material is about 12". That makes it like a wide tanktop width, but with a tight neck. Because of the shallow chest depth assumption, it also gapes badly at the sides of the pecs is you aren't a skinny tennage boy.The material is a medium weave-density dry-fit material with a slightly slick coating. It's thin and light, and slightly slick, but only as stretchy as a dry-fit. The weave density means you'll be able to see thru it slightly, you could clearly see my back tattoo right through the white material for instance. The material is very sturdy and will last a long time, and breathes very well.It's great for running outdoors in warm weather when you need high breathability but can't/won't go shirtless. It isn't good for casual wear since it's too ill fitting for a natural comfortable look and is aggressively athletic instead. It's also mediocre for weights since it is a little tight arou nd the neck and trying to do a shoulder press would be a little inhibited.

the shoulders and chest fit perfectly, but the bottom is kind of long.

Awesome shirt. Got it wet and it dried super fast. Usually wear a large in t-shirt but needed medium in this shirt as it is a bit more fitted. It doesn't cling to you, it's pretty loose. Very bright. If you are looking for a shirt to make you stand out in a crowd - this one will do it!

Me encantaron la talla exacta

Fue para regalar, y le gustó mucho para quien la compre, se ve de muy buena calidad

The quality and material are great I bought 2 and they are great

la tela lycra no es mi gusto, parece tela de mayas y te queda ajustada más no incómoda, solo no es mi gusto la devolví

Had to return it as although it fit just right (ordered a medium and usually a medium-large in most men’s clothing), the arm holes were just huge! So unless you’ve got Incredible Hulk sized pecks and shoulders to fill them out, you’ll look a bit daft going down the gym if you’re just an average Joe like me.
