Surprisingly good quality and cut.
Considering that this brand tends to be a bit hit-or-miss (mostly hit) I was apprehensive about the fit and sizing. These fit so well that I bought other colours and have no issue with the sleeve length (often cheaper brands have very short sleeves) nor with the length of the body of the shirt. They look great, the fabric quality is excellent, and the colours are compatible with a broad range of pants (you can't go past black pants, black jacket/blazer, and any colour of this underneath).

Nice feel
Special Size: Two Pack, Size: Medium, Color: A-wine Red/Dark Grey
I’m 5’8”, trim and athletic build. The sleeves are a tiny bit tight and would be unpleasant on a warmer than expected day, but for a cool day just fine. Nice fit. Feels pleasant to the touch.

Good fit, light weight, very comfortable
Special Size: Two Pack, Size: X-Large, Color: Black/Army Green
I've purchased several of these now and overall they seem like a decent buy for the price. They are very light weight and seem to retain their shape and avoid wrinkling when hung to dry after washing. Despite never seeing a clothes dryer however, the black variant still pilled up a bit after moderate use. There seems to be some variation in sizing: all the black and olive colored ones seem pretty consistent but the gray run small and the blue just a bit large (all purchased in XL, me at 6'3 and 225#)

Great with a great price
Special Size: Two Pack, Size: X-Large, Color: A-blue/Army Green
First off. I am female 5’10”. I thought the extra large fit great. The material is very soft and light. I think they’re warm though. I just washed them for the first time yesterday with dryer. Air dry. I’d like to see after a couple washes and know how the dryer affects it.
