Material: 80% Polyester/20% Spandex. There is so much to love about our Tech Stretch shirt. It pairs perfectly with our Tech Stretch Collection, has wrinkle resistance, easy and effortless snap-closures, and an oversize, flattering fit! But our favorite feature has to be the tech stretch fabric. With a soft, silky feel and four-way stretch, this is designed for all-day comfort (and style). Blue Sign Certified with moisture-wicking technology, Tech Stretch is created with a low-environmental impact, meaning you can feel as good as you'll look!
