As their official kit supplier, Arena has developed a range of elite swimwear, designed with & for the England swim team at the Commonwealth Games in Glasgow 2014. This is the same as England athletes compete in. The Powerskin Carbon-Flex emerged from a process that assimilates data & feedback from several sources, including individual Elite Team athlete preferences, further research & experimentation, & the exploration of alternative features to match varying swimmer needs. Carbon Cage means intelligent muscle compression. Lock down of the carbon fibres maximizes compression on over-extended zones, increasing support & control without compromising freedom of movement. Strategic placement of low profile bonded seams & elasticised tapes is designed to store potential energy, which is released during dives, kicks & turns to maximize efficiency, power, & speed. In the V-Flex system, seams have been moved from the side. Seam placement creates a flex-line across the hip flexors, offering less resistance during hip flexion on starts, turns, & breaststroke kicks. The system delivers complete freedom of movement around the hips, glutes, & shoulders, along with perfect fit & comfort. The rear seam creates a tension-line between the two anchor points, limiting stretch on this line & having a lifting effect on the back of the legs. This helps to keep the legs high in the water during freestyle, & to keep the knees from dropping during breaststroke & butterfly.
