Our Waffle is a medium weight, super stretchy, organic cotton spandex. "Waffle" here is referring to a fabric that is woven in such a way that it resembles a honeycomb. It is very absorbent and the honeycomb pattern allows air to flow freely through to cool off the person wearing such fabric. It's woven on a loom so it makes it more durable than other types of fibers. It makes perfect underlayers, hoodies, shirts, pants, or anything you want to make with it!
