The present invention relates to an adherent interface dressing intended for application directly to a wound. Said adherent interface dressing includes a non-adherent cohesive gel formed from a hydrophobic elastomeric matrix consisting of a styrene-(ethylene/butylene)-styrene or styrene-(ethylene/propylene)-styrene triblock elastomer optionally associated with a styrene-(ethylene/butylene) or styrene-(ethylene/propylene) diblock copolymer; said elastomer plasticized by means of a mineral oil, and containing dispersed therein a small quantity of hydrophilic particles of a hydrocolloid; and a flexible open-mesh fabric, said fabric including threads coated with the non-adherent cohesive gel such as to leave the meshes substantially unsealed, The fabric is a heat-set knit with weft yarns, said yarns being continuous multifilament yarns with non-elastic filaments, whereof the extensibility in the transverse direction measured in accordance with standard EN 13726-4 is between 0.01 and 0.5 N/cm.
