This non-medical mask has two layers. The outer is made with either of the green or tan CADPAT, or SAR Tech clothing material. The inner layer is tightly woven 100% cotton. There is a space between layers for extra filter material if needed. The mask also includes a removable wire nose piece to help fit the mask to the individual, and an adjustable elastic.
For sizing, the large generally fits men, while the medium generally fits women and teenagers.
All proceeds form the sale of masks is donated. I keep nothing back to cover the cost of materials.
