Abstract: The invention provides a holder (10) for scuba diving equipment. The holder (10) is attachable to a back pack for a buoyancy compensation device, and includes a back sheet (12) and a front sheet (14) connected to the back sheet (12) to define a pouch with an upper access opening (18). The holder (10) includes an elastic member which extends across an upper region (22) of the front sheet (14) so that the access opening (18) is expandable during insertion of scuba diving equipment into the pouch and subsequently contractible to retain the scuba diving equipment within the pouch.
