details about product: Non-Iron Poplin Short-Sleeve Shirt - Sky Blue

I'm sorry to hear that some of your non-iron shirts are harder to maintain crease free than others such as these non iron poplin and "iron required" linen shirts. Depending on how thick or fine a weave is will determine its crease resistance. The thinner the shirt, the easier it will be to crease. As you've chosen our finest weaves, the poplin and linen, it will be more vulnerable to creasing compared to our other weaves such as our midweight twill or heavy-weight Oxford. Our non-iron treatment, however, ensures that any shirt regardless of its weave will come out virtually crease-free from a 15-minute trip to the dryer. If you'd like to swap this over for one of the thicker shirts, like a twill or an Oxford, please do so by heading on over to www.ctshirts.com/rebound
