The Mares Loop second stage is compact and lightweight. It allows hose configuration on either the right or left side. An ‘under the shoulder’ hose position minimises the risk of it getting caught during a dive and reduces the effects of vibrations when kicking with fins. 

The new integrated S-VAD (Sagittal VAD) system combined with the special profile of the internal deflector and the addition of a second exhaust valve allow natural breathing at any depth. 

An excellent second stage which is reliable and ultra-light.
