With our newly improved back-and-better-than-ever Tailored fit option (more refined and slimmer throughout the sleeves & body without feeling restrictive), this No Iron Oxford may now truly be the best-made, longest-lasting No Iron shirt available. And it's surely one of the softest, thanks to American-grown Supima® cotton. We also sew gussets at the side seams for untucked wear, and — it's subtle, but significant — two pleats on the sleeve (rather than the former three) for less blousiness. As always, the fabric stays smooth for 30 washes without the touch of an iron.Supima is conscientiously sourced, American-grown cotton that's farmed to minimize environmental impact. The fibers are 50% longer than standard cotton, so yarns are stronger, softer, less prone to fraying or pilling, and hold color longer.
