CDC recommended 3 total layers (2 layers 100% woven cotton + 1 layer interwoven non-fusible interlacing); metal nose fitting; stretch cord, foldover elastic or cord elastic w/ toggle; Adult and Child sizes available. Improved face stitching to avoid "pucker" effect. Great fit & easy to adjust.


UPDATE: Mom has gifted me a sewing machine! Ahh the love! Get ready for more streamline stitches from the good ol' sewing machine.
