This special collaboration with Subzero is a buy one give one. With each purchase Flex will donate one mask to Model Citizen Fund. Model Citizen Fund is a non-profit organization that provides a platform where people can see a true and immediate cause and effect by donating backpacks with over 100 items inside to people around the world, giving them the tools and confidence to build/rebuild their lives.

All Masks are premium filtered masks with two layers of filter media, sewn into the middle of the mask: a carbon filter for odors, some ozone and VOC’s; and highly efficient class particle filter for protecting from inhaled microscopic particles including dust, pollen, shavings, mold, biologics, germs, and contaminants in poor air quality.

These masks are 100% cotton, washable & re-usable, made in the USA, and not for medical use. Please allow 7-10 days business days to ship.
