What’s the secret to the cirrus’ly soft sensation of these undies? High-tech Tencel Modal yarns so ultra-fine and silky smooth, they’re like nothing you’ve ever felt next to your skin. Renewable wood pulp is processed to create a revolutionary fiber that’s better for the planet – and incomparably soft, too. Closed-cycle production keeps potentially harmful chemicals out of the environment by indefinitely reusing processing agents – making it a sustainable alternative to other fibers. We’ve mixed this sublime fiber with stretchy spandex for a hugging fit that’s downright heavenly. Wicking and anti-stink? Of course. Plus chafe-proof flatlock stitching and strategically placed vented panels so you can feel the jet stream while you’re on cloud nine!
