* 98%cotto * Adults Size Masks - At Sinoped, we understand that a face mask is not a “one size fits most” - We also know that if you wear a mask it should be comfortable, fit properly, and provide proper protection which is why we came up with our High End 3-Ply Safety Masks in 2 sizes. This page shown is for adults. The size is Lenght 9inch, Width is 5 inch (ends width is 2.5inch). This is big enough for an adult's face. * 98% Cotton Masks- We know some adults with sensitive skin. Sinoped Face Masks are a Two-Layer Design – Outer layer and Inner Layer are 98% cotton – soft against the skin. Designed with high quality light weight fabric for maximum comfort. Our stretch ear loops allow for a snug and secure fit. * Our adult face mask can be as a sports face mask or athletic face mask because it is a breathe easy mask,that is made of two layers of cotton cloth, which is breathable and absorbs sweat. So you can also call it summer face masks or travel mask. * Our comfortable face masks are due to the 3D tailoring, your nose will not have a sense of pressure, this is very important when using him as a workout masks for gym. * In addition, the metal strip inside the mask makes the face mask close to the face and nose. It won't be like a flat mask - there are two big gaps under the eyes and between the nose bone.
