A nasal dilator. The nasal dilator includes a hollow, tubular body having open first and second ends that allows air to pass through. The tubular body is adapted to be positioned within a user's nostril, or nasal passageway, to maintain or increase the capacity to breathe through one's nostrils. The tubular body includes apertures positioned at intervals that allow hair and other nasal objects to extend within the tubular body. These apertures provide comfort in use. The nasal dilator remains within the nostril by friction fit, and may be selectively utilized in either, or both nostrils.
