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.

nice but doesn't last

Great feeling shirt but pills quickly after a few washes

Tall size!

Finally shirts for tall guys! Ordered a few of these and they’re great! Being 6’7” it can be difficult getting a good fit. You nailed it with these. Thank you! Now how about some more long sleeve shirts?

Bad material

I have a lot of under armour clothing that I like due to the style and high quality. Up to this point everything has been of high quality. This is one of the poorest quality shirts. Very thin material, so much that lighter colors are almost see through. After a few hours wearing the material became very itchy. Very disappointed in the poor cheap quality. Should be discontinued. Definitely has left a bad impression. Does not live up to the under armour standard I am used to.
