1. Rapid absorption with minimal swelling: The foam layer allows rapid absorption of both normal and viscous exudate     and it is better at handling exudate than comparable dressings .

3. Traps bacteria away from the wound: The superabsorbent fibres in the retention layer prevent exudate containing bacteria from re-entering the wound bed, even under compression    . The backing film prevents entry of external microorganisms larger than 25 micrometres  .

2. Maximises capacity by channelling exudate: Exudate is channelled away from the wound and over a wider area to increase moisture vapour loss and reduce swelling    .
