The Apeks XL4 OCEA is a lightweight, compact and highly efficient regulator designed for divers who value low weight, reliability and excellent cold-water performance. Based on the expedition-tested Apeks DS4 platform, it delivers outstanding breathing performance in a travel-friendly and minimalist design.
