AI insight
Based on specifications & design characteristics

The 360° swivel on the Rio II Nasal handles full rolls from side to side without torquing the mask off the nose — active sleepers appreciate not waking up to a displaced mask. The under-nose cushion keeps nasal bridge contact to zero, which is the most common source of morning red marks with standard nasal designs.
