CHECK THE SIZE CHART (in the image section above) The womens's Orca Predator Fullsleeve Tri Wetsuit employs various buoyancy technologies to both improve your position in the water and make you faster. This wetsuit employs various buoyancy technologies to both improve your position in the water and make you faster. The mid-to-bottom panels at the front and back of the suit will lift you in the water, whereas the top half of the suit €“ particularly around the arms and underarms €“ is thin enough to ensure that you do not feel constricted as you swim. The arms and underarms are just 0.88mm, meaning you have complete freedom of movement from your shoulders to help reduce fatigue. The core part of the Predator wetsuit is constructed from a stiffer material that may feel slightly unusual when on land, however once you enter the water this buoyancy will mimic the feeling of swimming on a surfboard. The panels are entirely waterproof meaning that no matter how long you swim; they will not get heavier. The Predator wetsuit has been coated in a smooth-skin so that water flows more easily over it, helping to reduce drag. By using a particular neoprene, designed with small bubbles of air, the suit offers 30% more buoyancy than other neoprenes in tactically selected areas to improve your posture and make your swim faster, more comfortable and each stroke more efficient. Features: ULTRA FLEXIBLE €“ the Predator is made from a stretchy nylon so the entire suit is flexible, however arms and underarms of just 0.88mm promote a natural stroke that helps to reduce fatigue. THERMODYNAMIC €“ although the suits top half is ultra thin, it has been lined with a titanium coating that will help to keep your arms warm and standardise your body temperature. VARIED BUOYANCY €“ the suit's 5mm core panel and 4mm sides encourage hip rotation and buoyancy around your middle and lower half. This will improve your posture in the water and make you faster, as your core muscles will have to do less work to keep you in the correct position to swim efficiently. CORE SUPPORT €“ the back and lower frontal panels are made of a slightly stiffer material to further support your core, saving you energy and reducing the risk of injury. The panels are completely impervious and so will provide support without getting heavier as you swim.
