As well as this, the Predator features Nano ICE; the fastest coating on the market gives you a performance edge. The Predator also uses Exo-Cell2, which is the latest upgrade to the very popular Exo-Cell. This material is 30% more buoyant than Aerodrome and has been utilised on the lumbar to give core buoyancy and aid with stability in the water. All new for 2013 is Pressure Function. 3mm (PF) on the calves and forearms aid bloodflow back to the heart and also reduce muscle oscillation. On the shoulders and arms 2mm (PF) helps reduce muscle oscillation whilst still providing excellent range of motion and flexibility.Features:*Low profile neck limits water entry, reduces chafing, reduces drag*Slipstream zip for low drag*Exo-cell 2 lumbar buoyancy system: optimum swim position for greater speed*Pressure function forearm and calf panels: increased blood flow and blood oxygenation from strategically placed pressure function panels at the body extremities*Pressure function shoulder panels: pressure function Yamamoto neoprene on shoulders and arm to reduce muscle oscillation and aid bloodflow from the extremities*44 cell Yamamoto neoprene: almost full body coverage of 44 cell*Speedway SCS flex panel: fast removal of suit enabling faster transition times*3D cut leg: contoured to fit shape of the calf for increased comfort*Design inspired by Orca namesake and muse, the apex predator of the ocean, the orca whale
