Designed to fit to the contours of the face. This mask is our best fitting model and contains 3 layers of cotton fabric over the nose and mouth. The lining is densely woven cotton ticking, printed outer layers are tightly woven quilting cotton. Stiff cotton canvas helps to hold the shape, keeping the mask away from the mouth and nose, allowing ease of breathing. Adjustable at the sides and under the chin. Proudly made on Roncesvalles.
