Breathe Easy in Uniqlo's New Airism Face Mask With three layers of protection, this mask was designed to be both protective and comfortable.

These masks have five layers to protect you from airborne particles, a 3-D structure to make breathing easy, and a nose strip for the perfect fit.

The masks are packed in “stone bags” that completely biodegrade in 14 months. CastleGrade’s form-fitted face masks come in two adult sizes. Most adults prefer size G9.
