A Mask Shaped by Science

The patent pending BendShape masks are general purpose masks. The entire surface of every BendShape Feather mask, and the textile portion of the BendShape Quartz mask, employ a full-surface filter engineered for:

*a ShapeFit that hugs the contours of your face while you speak, smile, and laugh with little-to-no adjustment;

*sharing smiles and clearer communication with an antifog transparent front;
*machine and hand washing; and

*better breathing and elocution thanks to our light, airy filter and a design that sits off of your face.

The BendShape mask line was developed by our multi-disciplinary engineering team led by 5 Ph.D.s with diverse expertise in textiles, applied materials, mechanical engineering, sensing and design.

BendShape Mask is proudly made in the USA.
