Core support from the neoprene helps you hold the position between drills. The wetsuit feel without the suit For pool training and warm open water, the Active-Flex recreates the body position a wetsuit gives you on race day. The accessible way in As the entry point to the range Zone3 invented, the Active-Flex covers the core job of buoyancy training at its most accessible. WHAT YOU’LL FEELPush off and your hips rise on their own. The water stops pulling at your legs, and suddenly there’s room to think about your stroke. You can kick, rotate, and drill exactly as you would on race day. For most swimmers this is the first time a flat body position feels effortless enough to build on.FITSnug fit with a drawstring waist that adjusts to size; unisex.WHY TRAIN WITH BUOYANCY?Why train with buoyancy?
