What people are saying
“We received our masks last week and love them! The straps are comfortable and I honestly don’t notice them. I feel very safe wearing my B2.”
- Julie Ostrow
“Quality construction, easy to use, well-packed, and well illustrated. Due to the small chamber created between the nose and mouth, breathing seems easier than multilayer cloth coverings.”
