Yes! We have tested Dear Kates air permeability alongside other leading brands of underwear (cotton and synthetic), and the results show that Dear Kates exhibit breathability comparable to regular non-functional garments. The difference is that Dear Kate underwear is moisture-wicking and anti-microbial, meaning bacteria doesn’t have a place to grow like it would in pantiliners. Several customers have told us they appreciate the security of Dear Kates while dealing with discomfort down there.
