Avant Gauze Non-Woven Non-Sterile Sponges. Avant Gauze is Medline's standard non-woven dressing. Compared to traditional cotton gauze, Avant Gauze helps to reduce the amount of lint that is produced and is less traumatic to fragile granulating wound tissue because it's virtually non-adherent. It also has significantly faster wicking ability which promotes a healthier healing environment. Discover the perfect balance between strength and absorbency in this rayon/polyester blend gauze.
