Phelps Diaphragm Organizer PDO

The PDO was designed to help organize your favorite diaphragms with ease. Simply slide your diaphragms in the slots provided to create a stacked series of calls that can be pulled out one at a time. The vented webbing system allows the diaphragms to breathe when stored, therefore allowing them to dry properly and be ready for use each and every time you're ready to call.
