The Manta Industries Regulator Necklace is derived from Technical Divers that had the need to keep their backup regulator close when needed. The Manta Industries Regulator Necklace attaches easily to any regulator second stage mouthpiece and allow the regulator to hang close under the chin. The Regulator Necklace is made of soft, yet durable, silicon and is perfectly designed to fit around a divers neck, with or without a hood.
