APEKS XL4 NITROX
100% O2 clean XL4 Regulator from Apeks is designed with the cold-water exploration diver in mind. Weighing in at a tiny 905g, the XL4 is the lightest ever cold-water regulator produced by Apeks - greatly reducing the risk of a free flow in low temperatures. Comes complete with hose. First stage with M26 thread.
