2XU P:2 Propel Wetsuit With 2XU's P:2 Propel Wetsuit, you'll have the flexibility, buoyancy and hydrodynamics to put in your fastest swim times; this is a top-end offering packed with performance technology. The rear zipper unzips top to bottom and the floating zip panel increases movement so you can increase your distance travelled per stroke. For an efficient stroke, you require full and unrestricted movement and this suit has a number of features to enhance this. Intermediate zone stretch panels ensure fluid movement and the internal lining has 520% stretch for lateral flexibility. The shoulder and arm panels are seamless while a silicone concave water entrapment zone further enhances distance per stroke. A rollbar construction increases core buoyancy and puts you in the optimum position for an efficient swim stroke, reducing body roll. 39 Cell 5mm thick neoprene in the front panel further enhances this by offering maximum buoyancy. The SCS silicone coating is hydrodynamic and reduces resistance, both when putting on and removing the suit, and in the water. In addition, SCS will improve your comfort, keep you warm and decrease fatigue so you can push harder for longer.
