Outswim the competition. Inspired by Blue Seventy's expert-level Helix, the Reaction is crafted for swimmers who aim to be at the front of the pack. Redesigned upper-body paneling reacts to your natural rotation, creating more power and distance with every stroke.

Premium Yamamoto neoprene and a unique single-piece shoulder design with no seams to get in your way give a fluid, uninterrupted range of motion, with ultra-flexible, thin neoprene in the arms for pure power through every phase of your swim.

• Reactive Stretch Technology (RST): thinner neoprene around the back and shoulders for flexibility, natural rotation and more distance per stroke
• S-Flex side panels make the suit easier to put on and give a comfortable, optimal fit
• S-Grip textured forearm panels for a better feel for the water and extra grip in the propulsion phase
• Smaller wrist cuffs for easier entry and exit, even over a large watch
• Quick-exit legs for faster transitions
