Nice Casual Dress Shirt
Color: Olive Green, Size: XX-Large
I own a few of these, and they’re really nice and comfortable. I was surprised by how heavy the fabric was, but overall, they make a great casual dress shirt.

No problem drying this shirt in a dryer at ultra-low setting
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.
