Apeks Black Sapphire

According to the UK-based manufacturer, the stunning-looking metal cover, which is machined from aircraft grade anodised metal, improves performance in cold water. First stage performance in cold water has also been improved with a heat-exchanger that comes fitted as a standard. Five ports allow for flexible hose routing, and a unique carbon-coloured hose with both a second and first stage swivel makes it more comfortable in use.
