The revolutionary R-EVO ONE is the first suit of its kind constructed from a single piece of R-EVO's ultra-lightweight woven fabric. This unique and innovative construction technology wraps the body for an unprecedented fit and eliminates the need for side-seams - thus increasing freedom of movement, and dramatically increasing durability and comfort. FREEDOM OF MOVEMENT: Constructed from a single piece of fabric with a bonded seam at the back, the absence of traditional side and upper-body seams provides uniform stretch throughout the suit and gives the swimmer complete freedom of movement and unmatched comfort. ADVANCED HYDRODYNAMICS: R-EVO One's ultra-lightweight fabric is so comfortable, it feels like a second skin….but don't be fooled. The R-EVO's ultra-fine threads and high-density weave combine to deliver excellent compression while dramatically reducing water absorption, therefore reducing surface drag and delivering streamlined hydrodynamics. EASY TO GET ON: The POWERSKIN R-EVO One's revolutionary single-piece design, with the exceptional multi-directional stretch properties of the R-EVO woven fabric, combine to deliver a suit that is one of the easiest-to-wear tech suits we've ever produced. With R-EVO, you'll Change Fast, and Swim Faster. FINA Approved.
