Simply an excellent shirt. The fabric feels soft to the skin, and is an ideal shirt in cool to colder weather. The fabric breathes nicely and does not make you sweat. The large 34-35 sleeve size I purchased is an exact fit. The fabric is slightly stretchy which is nice. I washed it in cold water, and dried it in an electric dryer at an ultra-low setting for 30 minutes and it came out perfect. No iron needed. No shrinkage. The label tells you not to dry the shirt in a dryer. I had no problems drying this shirt at the ultra-low setting! The fabric is 65% polyester, 30% viscose, 5% spandex. I bought 2 more of these excellent shirts.

Ok Black Shirt

Color: Black, Size: Large

I sent this shirt back due to the fabric not being particularly appealing. I haven't come across this smooth weeve before, but felt that if I am going to add a classic black shirt to my wardrobe, it needed to be better...
