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.

Fits horrible and looks wierd from the side, could make my own cutoff with scissors look better.

My Stats to help figure this out, measured per UA measuring guidelines: Height: 6'-2" Weight 192 lbs Chest: 44" Waist: 33" Size: Large, and it comes fitted. Athlete Type: Avid Weightlifter And out of my whole under armour collection (tremendous amount), this MK-1 Sleeveless shirt fits horrible, was too tight and I fit most all of my under armour stuff like a glove, except this. It looks weird/goofy from the side & front when wearing, especially viewing from the side looks terrible. Don't understand this MK-1 because I also have other fitted UA clothes and they fit way better. Please make the UA Threadborne Siro Muscle tank. The Siro fits like a dream, and looks killer compared to this. Size of my Siro's: Large Fit: Loose The Siro's hang off my chest and look great compared to this. I hope this review helps, thanks.

A little tight

This is a nice shirt that it runs just a little tight which gives me an incentive to lose some of my gut. I would recommend getting one size bigger than what you think you need for this particular shirt.

I don't like the cut

Decent product but it's cut funny around the arm holes. The shirt has a tendency to bunch or pucker up where the arm hole meets the chest. It is cut long also. I'm still deciding if I like the extra length. It does keep your shirt from riding up over your shorts.

Great for indoor and outdoor wear..

Comfortable and relaxing....Like the sleeveless look...

Perfect casual&work-out shirt

This is my favorite shirt. Great at the gym. And great for casual wear or as undershirt. Super comfortable, super cooling when sweating. And fit is great, not too tight, not too loose. Perfect. [This review was collected as part of a promotion.]

Keeps you cool, fits just right

Like this shirt a lot - not too tight, not too baggy. Really shuttles heat and perspiration away from you skin, keeping you cool. [This review was collected as part of a promotion.]

Sleeveless

Very comfortable and keeps you cool. A little on the expensive end however, I will purchase more. [This review was collected as part of a promotion.]
