length

The length of the black shirt i got is too long. it doesn't look that long in the picture but it was almost 1.5" too long on me. Didn't notice much difference in performance from a regular heatgear shirt. Not worth the additional cost over the regular heatgear shirt.

Not what I was looking for!

I love Under Armour but I'm frustrated that they don't keep some basics available in all sizes and colors all the time. I wear a 2XLT and came back to buy the Charged Cotton shirt that I love, but they're no longer available in my size. So I look for some alternatives and this was pretty much the only option in a 2XLT. I thought I'd give it a try try, even though it said fitted. I was disappointed. Very snug in the chest and shoulders. So then I tried the 3XLT and it fit better through the chest and shoulders but the neck and body were just too big and it looked goofy. I understand how a shirt like this could be beneficial and sought after by some, so by all means offer it, but please continue to offer your loose fit shirts.

MK-1

Most of my gym shirts are UA Raid. The MK-1 performs equally as well as the raid. The new cut seems to be tighter in the shoulders and under arms. Overall they will be a good gym shirt, but there will be an adjustment period getting use to the new fit.

Bought and returned

I’m 6’6” 205 and prefer UA’s L Tall sizes. I bought one Raid-style T-shirt in LT for work (police) and loved the fit but the tall sold out. I bought this MK-1 in LT instead as it has comparable specs online (fitted and mesh back) but in person the neckline was way too large/loose for an under shirt. Aside from that I like the body cut and feel and think it is a good stand-alone shirt for gym/workout wear if that’s your intent

mk1 short sleeve

Hi, the mk1 short sleeve is ausome but i'd like to see the waist a little snugger [tapered] love the mesh back , one of the best short sleeve shirts . I liked the raid shirts from a couple of years ago also and the cold gear reactor hybrid hoodie with the zip side pockets NOT the one with the snap buttons, that one was cut way too baggy in the waist and the snap buttons was a bad idea.

Good for but too long

It was a great fit for my body in a small size and I’m 5’8” the only thing that is not good is the shirt too long. Not everyone is 6’2”. ;) If they choose small size that means they might not tall as well.

So comfy. Perfect for everyday workout attire.

It fits fine for me. I'm 1.7m tall, got the medium size one. Only complaint is that it's too long.

I like it but the length is too long

I really like this shirt. It is a fitted so it fit tight to skin, If you want looser fit, try the UA tech shirts. My only problem with this MK-1 shirt is that it is too long in length (it covers my butt). If it was 2-3 inches shorter, it would have been a perfect fit. I am 5'8 height at 155 pounds and I got a size Small, the shirt fit nice but for bigger muscle guys maybe consider sizing up. I have to pull the bottom of the shirt up a little because it was too long but the material dries sweat quickly, good for wearing to the gym. If you don't mind the long length of the shirt then get it, but the long length can be a deal breaker for some.

Sizing Discrepancy

I bought this shirt originally in extra large and loved it. It worked so well that I lost 25lbs at the gym wearing it. Then went to order TWO of the shirts in large since I liked it so much. Then I get the Large and notice it has a wildly different fit. It isn't just tight, it is much shorter and has much shorter sleeves. Just weird to me that the sizing can be that much different. I still wear the extra large to this day even though I swim in it.

Long in the body, tight around chest and waist

I usually fit in an LT perfectly from almost any store. I have UA golf polos that fit perfect in LT, this shirt was a bit longer than I'd like and tighter than I had expected for a dad body. Works great as an undershirt that hugs the body, too long and tight if you want to wear as your top layer and the shirt in white is somewhat transparent. I'm keeping it as a base layer on colder days. I've worn it that way since getting it and it's perfect for that. I think I'm going to get a regular XL next time, expecting/hoping that will fit better as a outer layer t-shirt.
