Not Wrinkle-Free at All — Very Misleading Description
Color: Orange-pink, Size: Medium
I specifically purchased this clothing item because it was advertised as having “Wrinkle-Free Fabric.” Unfortunately, the actual result was very disappointing. After washing and drying it according to the care instructions, the entire garment came out covered in wrinkles. There was absolutely no sign of any wrinkle-free or anti-wrinkle effect. Every wash still requires ironing, which seriously contradicts the product description.
If you are buying this item because of the “Wrinkle-Free” claim, I would recommend thinking twice. The quality does not match the advertising at all.

Not Wrinkle Free
Color: Blue, Size: X-Large
I like these shirts because they are comfortable and cool. The microfiber fabric is smooth and breathable.
However, I find that they must be ironed while damp for best appearance. They do not dry wrinkle free. Also, small specks of lint from the washer seem to get caught in the microfiber weave.

Very nice shirt

Loved the quality and fit well. A little tighter in the chest than expected, but overall would buy again
