The Orca Women's Sonar Full Sleeve Wetsuit has been the class leading mid-range wetsuit for the last five years, thanks to its balance of performance and value for money. For people serious about open water swimming who are looking for a step up from an entry level wetsuit, the new generation Sonar offers more technology than ever before. The Sonar has been re-engineered to include panels of Orca's Aerodrome neoprene & 5mm panels that contain hundreds of air cavities that provide over 30% more buoyancy than an equivalent neoprene. The Aerodrome has been positioned in the small of the back and back calf area to help lift the torso and legs in the water. The buoyancy of the new Aerodrome panels is complimented by the seamless front 5mm Hydro Lift Body Panel. The Sonar's panel construction has also been modified to enhance flexibility in the shoulder and arm areas - with the Delta Stretch Shoulder Panel, Hyper Stretch Underarm and MultiStretch inner lining providing excellent range of movement. The Sonar also benefits from the comfortable new low profile neck seal, designed to sit flat against the neck, limiting water entry and reducing the incidence of chafing. Hydro Lift Buoyancy Cells are areas of padded foam, positioned on the upper forearm sleeve area to encourage a better arm position in the entry and catch phases of the stroke, increasing power and reducing fatigue. The 3mm stretch neoprene Speed Transition Calf Panel, allows an easier and quicker transition.
