Our standard wildrags are made 38 inches square. This extra size makes it easier to tie the knot and provides more protection for you, as well as making the rag more versatile. You can tie it and wear it in many different ways. Our wildrags have a serged edge. This produces a much stronger and durable rag than hemming. Silk, as a natural fabric, breathes. This adds to its comfort and practicality, plus silk is cool when its warm and warm when its cool. Wildrags aren't just for lookin' punchy, they really do provide protection against the elements.
