The XS Compact Second-Stage housing is made of durable non-corrosive hi-tech polymers, and has a dependable downstream demand valve mechanism with a lever that has a low coefficient of friction. The flow of air is channeled to the mouthpiece by injection, creating a venturi effect enhancing the performance. The 2’nd stage comes with a flow deviator that acts on the Venturi effect, with dive/pre-dive adjustment function. Large soft purge cover allows easy clearing of 2’nd stage and a comfortable silicone mouthpiece. The XS Compact Regulator weighs 4.76 oz.
