Apeks XL4 OCEA Regulator Grey 

The world’s first totally sustainably produced regulator, Apeks XL4 OCEA Regulator Grey  is a compact, lightweight regulator suitable for diving in all environments including cold water locations. Its design and low weight help reduce jaw fatigue on long dives.

XL4 Ocea also makes an ideal stage regulator which is perfect for the technical diver with a large amount of equipment.

The Apeks XL4 OCEA Regulator presents a new concept of the regulator to the diving market. One that comes with the inherent build quality and performance shared by all Apeks regulators but has the prime objective of being the first totally sustainably produced regulator available.

Every manufacturing detail has been considered and adjusted to ensure each material and process has been optimized in the pursuit of minimal environmental impact. Our partnership with PlasticBank establishes the Ocea as the world’s first ocean plastic negative regulator.
