An external nasal dilator comprising resilient and engagement elements is provided. A greater portion of the plan view surface area of the nasal dilator supports moisture vapor transmission (MVT) compared to prior art nasal dilators having a nearly identical plan view surface area and the same or similar functional resiliency. The engagement element surface area relative to the surface area of the resilient element of nasal dilators of the present invention is significantly greater compared to prior art nasal dilators having a nearly identical plan view surface area and the same or similar functional resiliency. In use the nasal dilator stabilizes and/or expands nasal passage outer wall tissues, and prevents said tissues from drawing inward during breathing.
