Good shirt minus pilling

Love UA shirts and have a few of the threadborne shirts, but they can be hit or miss. My newest threadborne siro shirt pills quite a lot, even though I only wash it with other UA /non-cotton workout clothing. My other UA shirts (some older, some newer) never pill, and I always wash all of them together. Seems like there is no rhyme or reason why this one does and my others don’t other than luck of the draw I guess. Overall a good shirt but you may wind up with one that decides to pill constantly.

Very comfortable fabric, but not as durable as Charged Cotton

Great t-shirt fabric for workouts and hot weather, and is super comfortable. It is thinner and not as durable as the Charged Cotton (sportstyle) which seems to have the best comfort, feel, and durability combination. The Smash Yellow (#772) is more like a mix of yellow and slime neon green color, not a true yellow. It is also a bit see through, compared to the other colors of the same material.

Comfortable and fashionable

My second shirt from UA and just as comfortable as advertised. I went with a coral colour and it is fantastic. Only issue is piling but I don't wash it separately or delicately, so can't complain too much.

Best T I’ve ever bought

I naught one thinking it was just going to be an at home wear piece, but it fits loose and was so comfortable, I will definitely be buying more of these.

Unlikely to purchase Threadborne again

I like the threadborne when I put it on. However, in the heat and sunlight any color seems to absorb the heat. Now when I start to sweat and there is a breeze it cools down very well. So, the net is unless you are sweating a lot or the t-shirt is wet to begin with and there is a breeze this shirt is really hot to run in... DFW TX...7/10...10am 89 degrees with a very slight breeze...2.75 mis... I think in long sleeves this would be a great shirt (material) to wear in the lake with UPF50 to protect from the sun...but you'd have to be in the lake not on it..

This shirt shrinks by at least a size after a few wears and washes

The shirt was very comfortable and fit nicely when I first received. I was concerned when I noticed the material fraying after the first few washes, which generally only develops after a year plus on high quality shirts. After a few more washes, I noticed that the shirt had drastically shrunk. The fit was tighter and it was a few inches shorter, now exposing my stomach during calistechics I'm going to avoid the threadborne and stick with the UA techs. I'm not sure why these shrunk so much since they're both 100% poly.

Nice shirt

I got this shirt and it is very comfortable. One of my favourites for the gym, nice colour and fit is awesome xl I would buy more of these shirts

Good Shirt

Lighter material shirt. Fit and feel is good. Neck line pills after a few washes and I never put it in the dryer. But all in all great Shirt.

Decent shirt but... does not wick sweat/breath as well as the other types do. Also, when you are sweaty and you want to take it off it tends to drag on your skin and it's difficult to remove compared to the other types of UA workout shirts.

Poor material

I have received five threadborne shirts and three of them have been itchy, the three that are itchy are all the same, the two that are not itchy have good breath ability and are comfortable but the three that are the same are itchy and a little big, I have worn under armor shirts for years now and I am not impressed with some of the threadborne shirts.
