L fit just right

Tee is good fitting, loose and/or tight where should be and opposite the case as well. I like the more tight fitting collar area vs similiar where the collar is loose and hangs low. This will make a great work out shirt or running shirt when temps warms up.

Light and airy

Excellent T for hot weather. Have only wore it a day at the cottage, but it was quite comfortable and definitely breaths well. I got a white one and it looks good to.


Son loves the shirt but it definitely runs a little small. Very light weight, almost transparent, great for working out.

Nice Fitted Work Out Shirt

This shirt is a great fit. Just like the description, next to skin without the squeeze. Very very quality light weight. I bought the black and it doesn't show through. Really like this to work out and run in.

Great Tee Shirt

Love this product. Great material that wicks moisture and dries fast. My go-to tee shirt for working out, hunting, and everyday use. I have had problems with odor building up in similar products. Even after washing the products retained an odor, this hasn't been a problem the threadborne material. Very comfortable, lightweight, and great fit.

Awesome for sweaty workouts!

So ventilated, that the white is basically see through. I bought a dark blue one at a department store to solve this problem. This Microthread idea is nice because it gives me so much room to move. Because its basically all mesh, it allows heat and sweat to escape, making me feel cooler. Definitely a go-to piece of gear.

Great quality

Purchased the phoenix fire color and on my first run a motorist said "you can't be missed in that shirt" which was the exact reason I purchased the color. Shirt fits well, works as intended and material is just fine.

Ordered Twice, Mixed Results

I've ordered the Men's UA Threadborne Streaker Short Sleeve on 2 different occasions. The first time, I order the blue shirt and I loved it. The material was soft (like a soft cotton feel) and very comfortable. That led me to order another shirt (arden green) a few months later. The second shirt felt like it was a totally different material (not nearly as soft) and it was very thin (you could see through it). It's still somewhat comfortable, but not what I was expecting. I don't know why there was a difference in material.

Smaller Fit than Siro

I purchased this shirt to see how it compares to the threadborne siro and I was very disappointed. The fit is quite a bit smaller so make sure you size up.

Transparent Shirt

The title says it all. The fabric on the shirt is so thin that you can see right through it. I guess this could be a good thing if you want to show off tattoos or are particularly proud of your nipples. However, for me, this kind of defeats the purpose of wearing a shirt in the first place. Since there isn't a rating for transparency, I reflected that in the comfort rating above. Although there is nothing wrong with the physical comfort, I would not feel comfortable wearing this shirt out in public. I ordered a small and the fit was a bit loose on me. I'm 5'11'' 145 lbs and was expecting a closer fit; not compression tight but just... closer. For me, the fit would be like ordering a size up at J. Crew, Gap, etc. If you have a muscular build, this might not be an issue. Despite the fit, I might have been willing to hold on to these as lounge shirts; however, I don't really see the point in wearing a transparent shirt. If I'm going to go that route, I'd rather not wear a shirt at all.
