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.

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...

Great comfort and style.
Color: Olive Green, Size: XX-Large
I recently purchased the COOFANDY Men’s Long Sleeve Wrinkle-Free Shirt, and I am beyond impressed! The fabric is soft, breathable, and has a great stretch, making it incredibly comfortable to wear all day. It truly lives up to its wrinkle-free claim—I can take it straight from the dryer or suitcase, and it still looks crisp and polished.
The fit is perfect for both formal and casual occasions. Whether I wear it with dress pants for work or jeans for a night out, it always looks sharp. The quality is outstanding for the price, and I love the variety of colors available. I intend to buy more of these shirts.
If you want a low-maintenance, stylish, and comfortable shirt, this is a fantastic choice. Highly recommend!
