Dynarex’s DynaGuard Waterproof Dressing is a sterile, multi-layered foam dressing that provides a warm moist healing environment. The waterproof top layer acts as a bacterial barrier, protecting the wound from any outside liquids that can cause infection. The inner foam layer absorbs drainage, while the low-adherent contact layer and adhesive non-woven fabric border provide protection to the wound bed and are gentle on the skin. 12/10/CS
