Built with the same top of the line materials as our award winning Helix the core short is designed to simulate the lift of a wetsuit resulting in a seamless adjustment to swimming on race day. It will improve distance per stroke, speed and body position all without the bulk and drag of a pull buoy. No longer are you limited in the strokes you can do. It provides improved swimming in all four strokes while allowing natural kick, hip rotation and turning. The core short is positioned to become the next great training tool for swimmers and triathletes of all abilities. It is durable and designed to withstand hours of pool and open water use.
