NWT storage / travel bag included! Packed with performance features and technology, the KONA has a GLIDEflex grooved panel in the chest to allow full expansion of your lungs. Many triathletes tend to “panic” breath at the start of the swim and the GLIDEflex panels release to allow the chest to expand for deeper breaths. Together with 2.0mm stretch arms and AQUAlift buoyancy technology that raises the hips to put the body in the most efficient swimming position, this wetsuit has been designed to increase speed and comfort in the water.
