While we understand and utilize the healing benefits of playa dust, we also acknowledge it's harm when one is exposed to it in excess. We are here to help you on your journey by providing you with the best lung protection for your earthly endeavors. Specifically aimed at the elements of the Black Rock desert (not only playa dust, but also Actively Burning Toxic Material SMoke! Yuk!), the masks we carry are the best choice in filtration effectiveness, breathing ease, and mothafuckin' style. . . We have tested these masks in the field ourselves year after year and would be happy to answer any questions you may have.
