2 different styles!
Light Back v Open Back
Both swimsuit styles utilise thin, ergonomic straps to ensure movement across the full range of motion while minimising drag. The Polyester/PBT and material technology create shape retention and has the added bonus of being fast drying.
Both styles are very similar. The only key difference is the Open Back style has a bigger opening at the back, coming down slightly lower and wider than the Light Back.
These swimmers run small so advise stepping up one size from what you would normally order.
