Want a dressier dress shirt? Start with better fiber. This No Iron Pinpoint is pure Supima cotton - the top 3% of the U.S. cotton crop. This yarn has the same ultra-fine "80s" width as our previous shirt, but now, with fewer fiber "ends" thanks to Supima s exceptional length, it s smoother and stronger than ever. Along with the no-iron finish that keeps the shirt looking just-pressed all day, we build in additional features like moisture wicking, to increase your comfort on muggy days. The closest Supima shirt we find on the market today doesn t have these features.
