The S270 features an air-balanced design patterned after the popular S620 Ti. Its compact casing and internal aerodynamics produce extremely low work of breathing. Designed to last in tough conditions, a fiberglass-reinforced nylon core combined with a PU outer layer result in a bulletproof anti-scratch casing. In addition to breathing performance, the S270 offers an effective purge and a dive/pre-dive switch. The exhaust tee is compact and efficient in minimising exhalation effort while directing bubbles out of the field of view. Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures. Technopolymer plastic barrel with a metal thread and a balanced valve helps save weight and provides a surface that ice crystals can’t grab onto when diving in extreme cold water. Dive/predive switch is easy to use even wearing thick gloves. More compact, lighter weight and better breathing performance than its S560 predecessor. Lightweight casing, made of a fiberglass-reinforced nylon core and a special PU outer layer, is extremely durable plus helps reduce jaw fatigue and improve diving comfort. The exhaust tee is compact and very efficient in minimising exhalation effort. Compact Hi-Flow mouthpiece is comfortable, made with FDA-approved (food grade) silicone, and features a large cross-section to maximize airflow. Super-flow hose features an oversized bore that allows more air to flow on each inhalation. CE certified to the latest EN250A European Standards for all diving conditions, including extreme cold water. Well-suited for diving classes, rental and professional accounts due to it bulletproof construction and solid breathing performance. Weight (without mouthpiece): 145g. Airflow at 200 bar: 1850 l/min
