So this is where we will go on a rant. We have seen a lot of companies market thin 100% cotton masks that are very "breathable". Let's keep in mind why we are all wearing masks to begin with - it is to filter out particulates and keep us, our loved ones and the community around us safe.
Being a medical scrubs brand at heart, we design products for the healthcare community. The outer layer in our masks is constructed from the same fabric we use in our scrubs, a proprietary 200 GSM Poly/Viscose/Spandex fabric. This fabric is water resistant which helps keep droplets (sneezes) out. It is also treated with antimicrobial, which essentially prevents the growth of bacteria, mold & mildew that may cause unpleasant odors, discoloration or deterioration of the fabric.
The inner layer is constructed from a 200gsm 100% cotton fabric. We include 3 replaceable PM2.5 Filters made from melt-blown polypropylene offering 95% Bacterial Filtration Efficiency (BFE) and 95% Particulate Filtration Efficiency (PFE) measurement at 0.1 microns.
So anytime you are wearing a mask that filters out >95% of particulates, it will take some getting used to :)
