DynaFoam Waterproof Bordered Foam dressing is a multi-layered waterproof dressing that provides a sterile, warm, moist healing environment. The waterproof top layer protects the wound from any outside liquids that may cause infection, while the inner foam layer absorbs drainage and the low-adherent contact layer helps protect the wound bed. It has an adhesive border that is gentle on skin. 12/10/CS
