The Apeks XL4+ is the perfect companion for technical exploration divers, especially those who favor cold water environments. This compact and lightweight regulator reduces jaw fatigue during lengthy, chilly dives. Engineered with an innovative over-molded endcap and environmental diaphragm, it effectively prevents ice build-up, making it an excellent stage regulator.

Ideal for divers focused on functionality and weight minimization, the XL4+ boasts a high-performance first stage with 2 high-pressure ports. This compact machined stage is based on the expedition-tested Apeks DS4 platform. The breakthrough over-molded endcap and environmental diaphragm prevent first-stage free flow in extreme conditions and protect against impact damage. A large surface area heat exchanger diaphragm clamp increases the gas temperature, enhancing cold water performance. The unique over-balanced diaphragm design ensures superior performance at depth.

The second stage features a high-performance pneumatically balanced lever-operated poppet valve, a large over-molded self-flushing and controllable purge button, and an easy-to-use ergonomic Venturi lever. The flexible white nylon braided hose provides better cold water performance than traditional rubber hoses, while the standard metallic hose connection ensures interchangeability. The Comfo-bite mouthpiece features a distinctive bridge that fits across the upper palate, eliminating the need for bite pressure.

With 2 HP and 4 MP ports, the Apeks XL4+ is an exceptional choice for technical exploration divers seeking top-notch performance and minimal weight in cold water conditions.
