ABSTRACT:
A nasal dilator comprising a backing substrate having a first face and a second face. On the first face, there is provided a fibrous pressure-sensitive adhesive layer that comprises an entangled web of pressure-sensitive adhesive fibers. The fibrous adhesive layer has a moisture vapor transmission rate (MVTR) of at least 1000 g/m.sup.2 /day, and an adhesion to skin of at least 20 g/2.5 cm. On the second face of the backing, there is provided a resilient spring which extends along the length of the backing and is attached to at least two end regions of the backing. The fibrous adhesive layer provides for a nasal dilator that can be repeatedly attached to a wearer's nose with minimal levels of skin damage or trauma upon removal and increased levels of comfort while being used.
