Wrinkle free? More like perma-wrinkle
I bought a similar shirt last year, and it was not as bad as this shirt, but the new one performs terrible. It feels like good quality and fits well. The problem is the stain free and the wrinkle free. The shirt stains, easily. However, due to whatever manufacturing process they use, traditional treatments do nothing. They just bead up and run off. My guess is whatever stained it in the first place is supposed to do this, but no. Worse is the wrinkle free. Just the opposite. I have followed the care instructions to the letter. But when the shirt comes out of the dryer it is no where ready to wear. So I iron it. I have no problem with this. After ironing I noticed that, while the shirt looks fine from a distance, up close you can see wrinkles all through the shirt. For instance, shirts wrinkle and crease on the sleeves when you roll up the cuffs (which I often do). Well, even after washing & ironing these wrinkles and creases are still there. Somewhat faintly, but they are there. So while the fabric appears ironed, you can see these wrinkles as if they are a pattern on the shirt. After several washings they are still there. Makes the shirt unwearable. Now I have to replace it.
