Threadborne Siro Twist T-Shirt is rated 2.4 out of 5 by 5.
Rated 2 out of 5 by from This is why I avoid 100% polyester... Bought 4 or 5 pieces from the new Threadborne line. Great fit and comfort, but you can't wear them outside. I don't understand why but 100% polyester shirts are notorious for absorbing outdoor odors. Usually if I'm looking to buy some clothing and it's poly, I make sure there is something else blended in, like spandex or cotton, to avoid the bad smell. I thought the new 100% poly Threadborne line with 'anti-odor' would be different, but I was wrong. They smell like a wet dog even after just 10 or 20 mins outside. I live in humid FL so maybe that has something to do with it. Back to being skeptical about 100% poly...

Rated 2 out of 5 by from Threadborne Everything is great about the Threadborne line, but for whatever reason, the shirts hold a TON of static electricity. Every time I wear them I need to throw some lotion on all over my body first.

Rated 2 out of 5 by from Not UA's Best T-Shirt The material is very soft, but the stitching around the shoulders is weird and uncomfortable. The sleeves are longer than the Tech tees and the body is cut much wider than all other UA shirts. I will not be ordering any more of this style.

Rated 1 out of 5 by from Doesn't stack up to UA Tech T-shirts Material is a little thicker then the UA Tech which is my favorite T-shirt. My opinion is that it does not dry as quick as the lighter UA Tech. Shirt sits a little tighter then other UA shirts that are sold as loose fitting. My biggest issue with the shirt are the weird seems going across the shoulders that create an awkward look.

Rated 5 out of 5 by from Great fit. I find this shirt and the rest of the collection are exactly what I like when it comes to comfort and performance. Bravo to ya'll.
