The Black Marlin is HEAD's most advanced suit. It is made of extremely flexible neoprene with unique compression around the core. A 4mm air cell panel on the front gives optimum buoyancy and the ideal water position. 3mm panels below the knee offer a more effective leg kick and 1.5mm around the arms and shoulders mean great flexibility and movement. A new low neck profile has been added for great comfort. New arrowed arm panels maximise the efficacy of strokes. Glideskin coating provides minimum resistance in the water. A reverse zipper enhances neck comfort and also improves reliability in the water, reducing the transition time in triathlon.
