A composite of a gel of swollen hydrocolloid dispersed in a pressure sensitive adhesive matrix is provided. The gel has a natural or synthetically derived hydrocolloid swollen with a non-volatile swelling agent, such that the gel may have a shear modu- lus of less than 6.2 x 10 6 dynes/cm2. The gel-adhesive composite has continued skin adhesion whether applied to or existing in dry or moist skin conditions. The gel contributes a high moisture vapor transmission rate to attempt to maintain dry skin conditions while the adhesive maintains skin adhesion. The gel-adhesive composite may be used in a variety of tape, dress- ing, bandage, drape, or other skin contacting usage and may optionally include antimicrobial agents to treat the skin while adhesion continues.
