Meet CottonTek™, our latest innovation that marries the crisp, natural feel of Wrinkle-Free cotton with the power of performance. We start with breathable cotton, then add in high-grade nylon that's sweat wicking and won't snag or pull like other materials. Then we add in plenty of stretch for all-day comfort. And to top it all off, we added micromineral technology that gives you a cool feeling from the very first wear.
This exclusive material is also machine washable, so you can skip the ironing and dry cleaning. Simply wash, dry, and wear this shirt to look sharp with zero extra effort—and get out the door faster in the morning. And of course, this style has the perfect untucked length, Stay-Put Collar, and single-needle side seams for a streamlined look. Wear it with our Chino Pants for an easy, go-to look.
