We call our Cotton Modal Blend an “underwear super-material” for a reason. It gives you the naturally soft, breathable feel of cotton with the lasting smoothness of TENCEL™ Modal. Plus stretch and minimized seams for comfort. And now, you can get Cotton meets TENCEL™ Modal (a fiber sourced mainly from beech tree pulp) to make a hybrid underwear super-material. Add a touch of spandex for stretch, and you’ve got a natural, luxe feel, with a resilience that helps to keep it feeling fresh and new, wash after wash. We also added a sturdy comfort waistband to help prevent rolling or digging throughout the day, took away all tags, minimized seams, and created a fit for real bodies: not-too-tight, not-too-loose, so it feels effortlessly supportive. If you’re between sizes, we recommend sizing up.
