The Esteem synergy® system features an innovative Adhesive Coupling Technology™. Instead of plastic rings, a foam adhesive allows the pouch to be securely attached to the baseplate on a clear plastic “Landing Zone” flange. The result is a low profile, flexible, two-piece system, whilst giving you the convenience of a one piece coupled with the versitility of a two-piece to suit your lifestyle needs. Pouch is designed for single use. Simply discard when full.
